A while back, in the CH
May 04 issue, I compared a vintage blued Ruger
Security-Six .357 Magnum
with a current blued GP100 .357 revolver. It was
interesting to note the differences that separated the
two designs by about 15 years.
The Security-Six was
Ruger's first double-action revolver, engineered to be
stronger and more durable than the competition's
mid-frame .357s. Police requirements in the 1970s
brought out both the hotter 125-grain jacketed hol-
lowpoints and a more realistic training regime that
had us actually qualifying with what we carried in the
duty gun, instead of with light .38 Special wad-
cutters, which had very little relation to either the
muzzle blast or the point-of- impact of the magnum
loads. Even in the Security-Six, the accelerated use
of hot magnum rounds brought on accelerated wear, and
the design was not cost effective to produce. The
GP100 line replaced the SS in the late 1980s. The GP
was beefier in critical areas of the frame, cylinder
and barrel, while still holding close to the same
overall size.
Shooting both four-inch
guns for the write-up gave me a chance to compare
performance in accuracy and handling, and left me
preferring the handling and heft of the older
Security-Six, but not minding the extra strength of
the GP. I liked the responsiveness of the lighter
barrel on my SS. It's livelier in quickly handling
multiple targets and feels quite well balanced. The
GPs with their much heftier barrels and full-length
underbarrellug, have always struck me as being very
muzzle-heavy, and just didn't balance well for me.
This is pure- ly a subjective impression, and the
heavier GP barrel does make a marked difference in
recoil recovery. Accuracy was about the same for both
guns, so that wasn't a factor in either direction. I
would much like to see Ruger pro-duce a lighter,
"skinny" barreled, non- underlugged version
of the GP with fixed sights, but they don't, and that
brings us right here.
Cylinder & Slide
Bill Laughridge's
Cylinder & Slide Shop has established something of
an annual tradition for me. Each year for the past
four, I've sent a gun to C&S for one of their
custom makeovers, and the results are four of the
finest guns I own. Number Five was due, and it wasn't
too long after the smoke cleared from the two-gun
Ruger .357 project that the light bulb appeared over
my head. Can the GP100 be improved a bit? An email to
C&S brought a return message saying, "Sure
can!"
The project was
assigned to (actually, grabbed with both hands by)
Ralph Gutekunst, who worked together with me on my
last project. After further emails and phone
conversations we came up with a laundry list for the
Ruger that would transform an already good revolver
into a better one. Nothing outrageous, nothing extraneous-just some practical modifications to
improve performance and handling beyond what the
factory can do at the price levels set for the model.
I think Ralph was actually more enthusiastic about the
idea than I was, and that's always much better than
hearing a custom gunsmith say, "You wanna do
what??????!!!!!"
GP100 Makeover
First item on the list
was that barrel lug. Gotta go, and go it went.
Next up was the sights.
Ruger factory sights on the GP100s are adequate for
many uses and most people, but they can be
tremendously improved for us older geezers who can't
find black-on-black on dark targets in a hurry
anymore. Years ago, when I could still focus clearly
on both front and rear handgun sights, I pretty much
scorned the bright-colored front ramp inserts and
white outline rear notches. Real men just didn't need
that kind of foo-foo stuff. But...Time catches up with
all of us eventually, and I've been duly caught up
with. Nowadays I need either lots of light on both
sides of the post in the notch, or something else to
help my eye differentiate between the two. More and
more, I'm finding that there was something to those
inserts and outlines after all, and more and more, my
handguns are beginning to reflect that where possible.
We dis- cussed sights, and agreed that we were
unlikely to find anything much better for the Ruger
than Hamilton Bowen's Rough Country all-steel sights.
The front sight on the GP is changeable, by depressing
a plunger above the muzzle and removing it, and Bowen
Ruger sights are drop-in replacements that don't
require any alteration to the gun itself. Hamilton
supplied a set for the GP, and Ralph installed a
flat-faced gold bead in the front post that stands out
well in most lighting and contrasts brightly with the
white outlined rear notch. The sights are very rugged,
fully adjustable, and provide a quick pickup at speed
if necessary. Perfect for my eyes, and a marked
improvement for an outdoors carry gun.
The factory triggers
are fair, but tend to be a little on the heavy side.
Ralph took the single-action pull from 4.25 down to
2.75 pounds, and the DA pull is plenty smooth.
Absolute reliability with any and all primer brands
was a must on a defensive handgun, and there wasn't a
single problem even with the harder CCI primers in one
of the factory test loads at the range. Too often,
reliability suffers if you're not careful in
lightening springs during action work-we're good here.
The last review was
done with a blued GP to match the blued Security- Six,
but for a keeper stainless steel seemed like a better
all-weather way to go. Even the brushed stainless
factory finish was brighter than I wanted, so a more
subdued bead blasted finish was requested. There
aren't many sharp edges on a GP100, but the rear corners of the trigger are sharp enough to shave with and
the hammer spur can remove skin if you're not careful.
Prior to the bead blasting, the gun got a carry bevel
package that rounded those off, along with the
cylinder latch thumbpiece. I prefer a smooth-faced
rounded trigger on my DA revolvers - this one was
rounded and polished brightly.
Other odds and ends
included re- crowning the muzzle to an 11-degree
"dish", chamfering the chambers for easier
speed loader use, and a semi- Fitz triggerguard. Fitz
what? In the first half of the 1900s, J. H.
Fitz-Gerald was a showman, ballistics expert, gunsmith, and Colt rep famous for his Fitz
Specials-revolvers with short barrels and
triggerguards completely cut away from the trigger
forward to the frame. The idea behind that
triggerguard modification was to put the finger on the
trigger right now, without the guard getting in the
way to slow the process down. He frequently carried a
matched pair of Fitz Special Colt New Service .45s in
specially lined pants pockets, and Fitz Special Police
Positives and Detective Specials in .38 caliber were
popular for a while among dedicated pistoleros of the
era. Today, a true Fitz Special would be labeled
either Collector's Item or Lawsuit Pending. But, if
you find yourself with gun in hand and finger off
trigger, for whatever reason, the theory is that
removing about half the width of the triggerguard on
the left or right side just forward of the trigger
(depending on a right-hand- ed or left-handed shooter)
gives you marginally less obstructed access for a
quick access to the trigger without running into the
guard enroute. A semi- Fitz treatment may help
fractionally while still maintaining the reason the
guard was invented in the first place- protecting the
trigger from being nudged and fired accidentally.
The final modification
on the list was a very simple one even I could handle
(literally) when the GP100 came back. Ruger equips the
GP100s with two different versions of their
Santoprene/walnut grips. The adjustable-sighted guns
get the bigger grips, the fixed-sighted guns get
slightly smaller and more rounded grips with a
different profile and feel in the hand. After owning
and shooting both over the years, I've come to prefer
the overall fit of the smaller grips.
So, having worked all
that out, I shipped a brand new stainless fourinch
GP100 off to Cylinder & Slide, arranged for the
sights with Hamilton Bowen, got a fixed-sight grip on
the way from Ruger, and settled in for the hardest
part...the wait. Finally, a call from C&S to say
the Ruger was on its way home, and it was time to
round up the gear and head for the gravel pit.
How It Shoots
Much of the .357's
reputation as a hard-hitting medium bore magnum was
built around a 158-grain bullet. Today we've got
several very good factory rounds to choose from in
other bullet weights. This particular GP was set up as
an outdoors, or trail, gun but could easily pull duty
as a concealed carry piece. It's not too heavy for
daily CCW carry with lighter bullets, and it's not too
light for the woods with heavier bullets.
I took six commercial
loads to the pit along with two .38 Special loads for
accuracy testing at 25 yards on my Outers Pistol
Perch.
You can actually go
even lower, but I don't see much use in anything below
a 11 O-grain bullet in the caliber. If you want to
shoot squirrels with a lighter bullet, you don't need
a .357 Magnum handgun. The 110s and 125s were
developed mostly for law enforcement use, and even
though the 1 25s widely eclipsed them in popularity
(and usually in performance) you still see a few
people carrying the 110s for self- defense because of
the lower recoil. The 158-grainer is the standard, and
the 180-grainer makes a good penetrator with the
right bullet type. All four weights were included to
see how the GP100 would cover the field. There are
also many people who buy a .357 Magnum revolver for
its strength, but shoot more .38 Specials through it
than anything else, and some .357 chambered guns shoot
.38s better than others.
From the rest, the
Ruger shot well enough for my purposes. Ralph tells me
he can probably tweak it a little further, but the
best five-shot groups are all I'll need in this trail
gun.
The Ruger was very
pleasant and easy at the bench. Recoil was stiffest
with the Hornady and Speer loads, but the .357 Magnum,
even in a relatively light revolver like this one, is
not a major kicker. The .357's famous muzzle blast has
been tamed somewhat with more modern powders, but it
was still severe with the Gold Dots whose muzzle
flash was visible in broad daylight. I've noted this
before with the Gold Dot round -it's a good performer
and I keep hoping Speer will incorporate a flash
retardant powder one of these days, it'll blind you at
night. Otherwise, the 110-grain Remington was very
mild, the 180-grain Remington wasn't as hard on the
hand as you'd think it would be, and the Winchester
.38 Special 158-grain lead semi-wadcutter was a very
consistent and low-recoil- ing load.
The point-of-impact
varied by about six inches between the 1 25 and 180-
grain bullets. Lighter loads lower, heavier loads
higher, and that's why we have adjustable sights. You
can swap back and forth between bullet weights in this
gun without giving up much to accuracy, but just
remember to set the sights to match your regular carry
load if you ever have to use it for self- defense.
The GP was quite
controllable under double-action rapid fire. It's not
as light out front as the Security-Six. It still has a
heavy barrel that helps with recoil, but it's better
balanced than it was with the extra weight of the full
barrel lug. After accuracy testing was done, I moved
up to ten feet from the target stand and had no
trouble getting a 4.75-inch six-shot group with the
Blazers, and a 5-inch group with a mixed cylinder, on
DA speed dumps.
Works for me.
Trail Gear
For trail carry, the
GP100 rides perfectly in the same holster we used
for the previous GP review, Bianchi's classic
leather 5BHL high-ride thumb break. In these days of
dwindling revolver holster choices, this remains one
of the best production models at $89.50. One of the
more comfortable and lightweight nylon belts to hang
it on is Bianchi's Model 7225 ErgoTek for $62.
Designed for police, you don't have to be one to use
it, and the inside padding helps ease the load on a
sunny spring hike. Speedloader pouches are likewise
drying up, get yours while they're still available.
The $31.25 synthetic 7901 AccuMold double pouch fits
my favorite HKS speed loaders, and old habits from my
early working days die hard, I still carry two double
pouches.
The SOG SEAL Revolver,
designed by Robbie Robertson, makes a fine lightweight
trail partner for the GP. Like the Ruger revolver, the
SOG Revolver is also stainless and corrosion resistant. One of the more sensibly
innovative designs
I've seen, it offers the genuine utility of two
blades in one fixed-blade (sorta) knife. The
Revolver's rotating blade locks into position with
either a cutting blade out or a saw blade out. This is
not a gimmick for the gullible, it's a serious
knife, made of AUS-8 stainless with very aggressive
saw teeth, and the company offers both well-designed
leather and Kydex sheaths. The Revolver is also built
with other blade types such as a tanto and hunting
version with guthook main blade. At six ounces with
lytel handle, it retails for $82.95.
For rough terrain,
steep trails, crossing running water, and general
hiking support, a good staff is well worth its weight,
which, in the case of Stoney Point's PoleCat Outback I
staff, is about 7 ounces. Made of hard-tempered
aircraft aluminum alloy, the 48-inch Outback I is an
outgrowth of the Stoney Point shooting stick line, and
features an oversized closed cell foam handgrip and
woven nylon wrist strap at the top. At the bottom, the
rubber tip can be removed to use the carbide tip for
better traction on rock and ice. It's a very handy
bargain at $19.95, and we have three PoleCats here at
home.

Final Notes
So, that's our Cylinder
& Slide project for this year, one of the best
trail guns going. As usual, the quality of the work is
first rate. The better-balanced and rugged GP carries
light with good support gear, the caliber is
sufficient to solve many hostile outdoor problems
(south of Alaska) with the right bullet choice, the
sights are much improved, and the smooth rounded grips
are extremely comfortable in a mid-sized hand. At 37
ounces, it's not quite a 35.5-ounce Security-Six, but
it's not quite a normal 39.5-ounce GP100 either. The
result is less weight than the current
adjustable-sighted GP100, with better sights than the
lighter 36-ounce fixed-sight GP. My thanks and
appreciation to C&S, Hamilton Bowen, and Ruger for
all their help.
The cost? $845 for the
package (excluding the GP100), but as always, you can
pick and choose which parts you'd like done to your
own gun, and I'd heartily recommend at least the
barrel work and Bowen sights, if you don't want to go
the whole route right now. (Prices have

The often
under-appreciated Ruger GP100 is a solid performer,
and you won't go wrong with these folks if you're
interested in maximizing yours. .
