It was only a matter of time before Glock pistols began appearing
at action pistol matches. As the popularity of the Glock grew
among IPSC/action shooters, the folks at Glock began to take
notice. They realized that here was an untapped market; and
after due consideration, they felt it was one that would be
worthwhile to pursue. In 1986, in an attempt to garner a share
of this growing market, Glock introduced a new pistol aimed at
the European action-pistol enthusiast, the Glock 17L. The Glock
17L had all the basic characteristics of the regular Glock 17: polymer
frame, "safe action" trigger, seventeen-round magazines, etc.
But is had several new design features aimed directly at the
competitive shooter: a longer slide with a 6-inch barrel, extended
magazine release, and a 3.5-pound trigger pull. The front quarter
of the longer slide was open on top, and the barrel had three
slots cut crosswise near the muzzle, angled forward. These
were intended to vent some of the powder gasses upward, to
help hold down the muzzle and reduce muzzle flip, as does the
muzzle compensator on a custom built race/pin gun.
The Glock 17L worked - the muzzle slots and added weight of
the longer slide reduced the recoil and muzzle flip of the 9xl9
cartridge considerably. The lighter trigger, longer sight radius
and extended magazine-release made for precise shooting and
rapid reloads, a must for IPSC faction shooting. The Glock 17L
had all the makings of a factory race-gun except for one thing -
the 9xl9 cartridge. For the European shooter this was not an
insurmountable problem as they could shoot 9mm "Major" loads.
But due to USPSA restrictions, American 17L shooters could not
compete on an equal footing with other race guns, most of which
were now chambered for cartridges such as the .38 Super or 9x21mm.
The creation of Limited Class by USPSA/IPSC was a boon for
those who wished to compete with their Glock pistols. The
rules specifically forbade the use of such exotic equipment as
electronic sights, compensators, weights, etc. Competitors were
basically limited to stock handguns with a limited (see, that's
how it got its name) amount of approved modifications. The
Glock, with its excellent ergonomics, high-capacity magazines
and ease of operation, was a natural for this kind of competition.
Glock pistols became so popular that, in some places, Limited
matches were referred to as "Glock owners' club meetings." In
1992, USPSA modified Limited Class rules at the request of that
segment of their membership who felt that Limited Class ought
to be restricted to really "practical" pistols shooting practical
cartridges. The new Limited Class regulations state, "Only
those calibers that are produced by at least three commercial
ammunition manufacturers, that are generally available at
retailers across the country and that make major power factor
in commercial form may be scored as Major." This pretty much
put an end to shooters trying to make major in Limited Class
with any autopistol cartridge under .40 caliber (10mm).
One other development in the firearms field made a major impact
on Glock - the .40 S&W cartridge. The introduction of this new
autopistol round was an instant success, and in 1990 Glock was
the first company to have .40 S&W pistols on the market, the .40
S&W Glock 22 and Glock 23 pistols. They quickly became Glock's
biggest sellers and were a driving force in weaning U.S. law
enforcement agencies away from the 9xl9 and into the arms
of the .40 S&W cartridge. For the Limited Class Glock shooter
the G22 was equally attractive. Here was his favorite pistol design,
chambered for a cartridge capable of making major power factor.
And unlike many of the custom built, high-capacity .45s that were
becoming more popular in Limited Class, it did not require one to
pay a custom gunsmith to modify it. It was ready to go out of
the box. But the Glock 22 had one disadvantage as far as the
serious IPSC competitor was concerned - its trigger pull. The
Glock 22, like the earlier 17, is only available with "duty" triggers,
the lightest of them having a five-pound pull. Glock does not
sell the lighter 17L trigger units for retrofitting to guns - a wise
decision in our lawsuit crazy society. What serious Glock competitors
wanted was a Glock 22 with a lighter trigger, while others suggested
that Glock consider introducing a long slide .45 with a compensator
system so that those who wanted to could use their Glocks in
Open Class.
Gun Details
Well, their wishes were granted when Glock introduced the Glock
24 series of pistols at the 1994 SHOT Show. At first glance, the
Glock 24 appears to be just another Glock 17L. But one only needs
to look at the bigger hole in the end of the barrel to know that
here is a "real" pistol. The Glock 24 has an overall length of 8.85
inches with a six-inch barrel. Height, including the magazine, is
5.45 inches, and it weighs 26.5 ounces unloaded, 2.2 ounces more
than the Glock 17L. The grip has impressed checkering on front
and rear for a fim grip. It has the same 3.5-pound trigger and
extended magazine release as the Glock 17L and is available with
either fixed or adjustable sights. Magazines made before President
Clinton's infamous Crime Bill held 15 rounds, while later pistols come
with 10-rounders. Even with the lower capacity magazine, with
one up the spout, you ought to have enough rounds to solve almost
any IPSC course "problem," if you do your part. And like all new
Glock magazines, the G24's fall free of the gun when the release
is pressed, even when fully loaded. But Glock had one more surprise;
the Glock 24 was available in two versions: plain barrel (24) or
vented barrel (24C). The plain barrel Glock 24 meets all USPSA
rules for use in Limited Class matches and is ideally suited for that
purpose. The vented barrel Glock 24C is aimed (excuse the pun)
directly at IPSC Open Class, and to a lesser degree at that other
action pistol sport, bowling pin shooting.
The Glock 24C's barrel venting system is completely different from
the earlier Glock l7Ls. Beginning 2 7/8 inches aft of the chamber
are a series of four oval vents of increasing size cut into the top
of the barrel, with the last one being 1 1/8 inches back from the
muzzle. Powder gases are vented up out of each hole in tum as
the bullet travels down the barrel. Gas pressure is lowered as the
bullet travels past each vent hole, making it necessary for the next
one to be larger to vent out a suitable amount of gas so as to continue
the action of forcing down the barrel and reducing muzzle flip. The
theory of the Glock 24Cs barrel vents is very similar to that of the
"Hybrid" compensator system, which is finding increasing favor among
serious action pistol shooters.
As a confirmed "Glocker" I was anxious to get my hands on one
of the new 24s. The folks at Glock, Inc., in Smyrna, Georgia, kindly
supplied me with one of the vented barrel Glock 24Cs to test. When
the pistol arrived, the first thing I did was compare it to my Glock
17L. Except for the uncheckered grips on my early 17L, there was
nothing to tell the two pistols apart at first glance. But I do have
to admit that the 24, which was a new gun right off the assembly
line, had a much nicer trigger than my well used 17L, a fact much
appreciated when I started using it at IPSC and bowling pin matches.
The pistol came with Glock's standard fixed sights, featuring a white
dot front and white outlined rear notch. But enough looking - pistols
are made for shooting, so it was off to my gun club to try it out. I
took along several necessities: my adjustable pistol rest, targets, my
Chrony Model F-1 chronograph and a supply of .40 S&W ammunition.
I had a fairly varied assortment of test ammo, including Winchester,
Remington, Hansen and some remanufactured ammo from 3-D
Ammunition & Bullet Co. I arranged to borrow a Glock 22 from my
friend Mark Craven so I could compare velocities between the
standard length and long-barreled Glocks.
How It Shoots
I first test fired each brand of ammunition for accuracy, shooting
from a rest at 50 feet; the results are shown on the chart. In spite
of having fixed sights, the Glock shot all of the ammunition to point
of aim, only varying slightly in elevation, and gave me more than
adequate groups, the best five-shot group of the day being provided
by the Winchester 180-grain Subsonic - an extremely pleasing one
inch! I then fired each type of ammo over my Chrony F-1, firing
the Glock 22 first, and repeating the process with the Glock 24C.
As can be seen in the chart, the Glock 24Cs longer barrel provided
increased muzzle velocities, ranging anywhere from 25 to 60 feet
per second faster. Shooting the 24 and 22 side by side, I noted a
big difference in muzzle flip with the Glock 24C. It was quite obvious
that, the extra weight and vented barrel system do perform as claimed.
While those cartridges marked with an asterix (see table) did not
make the USPSA Major power factor of 175 (bullet weight x velocity
/ 1000) from the standard length Glock 22, all the ammunition tested
easily made Major out of the longer-barreled Glock 24C. As shooters
of the .45 ACP know, it is very nice to be able to load ammunition
that makes Major without resorting to the chemistry, ballistic computer
programs, alchemy and dumb luck that many of the smaller calibers
require. The longer-barreled Glock 24C enables .40 S&W shooters
to enjoy this same sense of security with their ammunition. There
have also been reports about the .40 S&W not being a very accurate
cartridge. Now, I will admit right up front that this Glock 24C is
the flrst .40 S&W pistol I've had any extensive experience with,
but I found little to complain about as far as its accuracy went.
My only comment is that this particular pistol had a definite
preference for the heavier 180-grain bullets, which consistently
shot smaller groups than the cartridges loaded with the lighter
155-grain slugs, some of which were downright impressive.
To finish things off, I set up an IPSC-style target and proceeded
to try the 24 in a bit of "combat" style shooting, drawing from
a holster and firing a series of double taps. For leather I used
one of the new Australian-made Hellweg Competition Speed
Holsters (Hellweg, Ltd., 40356 Oak Park Way, Suite H, Dept CH,
Oakhurst, CA 93644; Ph. 800-955-4486). This rig is just the thing
for Glock shooters; it holds the pistol securely but allows a very
quick and smooth draw. The holster is adjustable for height and
rake angle, which came in very handy with the long-nosed Glock
24C, as I was able to lower the holster so that, when drawing
the long 24, I did not have to pull the pistol all the way up into
my armpit, as a regular belt height holster would have required
(note: this one holster will also fit the Glock 17, 17L, 19, 22 and 23).
This type of shooting is where the 24s lighter trigger, longer
sight radius, weight and vented barrel really came into their
own. As with all Glocks, the 24s ergonomics are excellent, and
it was easy to get a fast, secure grip on the draw, and it pointed
very naturally. Muzzle flip was almost nonexistent. Such reduced
muzzle flip allowed quick recovery, and rapid double-taps were
easy to perform. The extended magazine release and the free-falling
Glock magazines were very convenient and made rapid reloads
a cinch.
Glock 24C Impressions
Over the past several months, I have used the Glock 24C at many
of the IPSC, steel pin and bowling pin matches in my area. I have
also competed with it in several of the matches sponsored by the
Glock Sport Shooting Foundation (G.S.S.F). It always attracts the
attention of other shooters, especially my fellow Glockers, who
are suitably impressed with how well the ported barrel performs
the task of reducing muzzle flip.
All in all, I was quite impressed with the Glock 24C. For an
out-of-the-box pistol, accuracy is better than one would expect,
and handling characteristics are excellent. I have not been
disappointed at all with its performance so far. For someone
thinking of trying their hand at any of the action pistol shooting
sports, the Glock 24C deserves a long, hard look. An out-of-the-box
pistol with most of the special modifications that action pistol
shooting requires enables the shooter to start practicing right
away instead of waiting for his gun to get back from the gunsmith.
And after all, what are we in this sport for, shooting or marking
time?
