The Glock Model 21, Generation “2.5” .45 Auto
Our son Josh recently picked up a used Glock 21 from Terry’s Gun Specialty The gun is in good condition and the price was very reasonable. I drooled over it awhile myself, but passed because I needed something better suited to concealed carry. At 8 ¼ inches long and 38 ½ ounces loaded, the Glock 21 is a BIG 45 Auto. The Model 21 was introduced about 1990, but this gun’s CKW prefix indicates September 1997 production. It is a Generation 2 1/2 gun with the finger-groove frame but no accessory rail, as seen on current Glocks. Its night sights have plenty of life left in them.
The gun’s only problem was that someone had installed a Ghost 3.5 # connector. The resulting pull was too light for a carry gun and to make matters worse, the second stage of the pull was mushy and unpredictable. This is Josh’s first Glock and he wasn’t comfortable carrying it IWB, so I swapped out an OEM connector. This improved the second stage immensely and added only a pound to the pull
Josh agreed to have his pistol reviewed for the Glock Files at www.thesixgunjournal.net This was accomplished on January 5th and range conditions were, well, ‘January in Missouri’. It was spitting an icy mix, the temp around 37 with a 15 mph wind insuring that you knew it was winter. I did not set up a chronograph but used loads that I’ve already tested.
At 25 yards I fired five rounds standing unsupported from a modified Weaver stance. I used my bulk .45 Auto reload consisting of Missouri Bullet’s 225 grain cast ‘Flathead’ over 5.4 grains of W231, loaded to 1.220” OAL with CCI primers. It averages 840.8 fps from 1911’s and shot pretty close to the sights; the left grouping was probably me milking the trigger.
At 50 yards I fired five rounds of Federal’s ‘Champion’ 230 grain FMJ economy load, which has proved accurate in every .45 Auto I’ve tried it in. Shooting was done from a canvas hunting chair, using my range bag for a rest. I called a low flyer, which ruined a nice group; but the four I didn’t screw up went into 4 ¼ inches. The group did print a little high.
Glock pistols have achieved an enviable reputation for reliability and the G21 lived up to it. About four more magazines of odd & end .45 ammo went down its bore and no malfunctions occurred. Like other Glocks I’ve tested, it possessed sufficient mechanical accuracy for 50 yard head shots. There is really nothing else to ask of a full-size service pistol.
