Big-Bore GEN 4
The Glock G21 .45 ACP.
My how time flies. Glock pistols still seem like the new kid on the block to me, yet they are already in the 4th generation. Actually, Glocks haven’t changed much since they were first introduced, at least not in terms of operating features and function. For the most part, newer versions have incorporated relatively minor handling features. I like this approach. One reason I like guns is they have remained relatively unchanged over the years. I hate buying something and a few months later having it become obsolete when a “new improved” model appears. I get enough of that from cameras and computers.
The only feature which might have caused me to trade in an older Glock for a new model was the addition of accessory frame rails. On a concealed carry gun I can do without the rail but on a home-defense pistol it’s nice to have the option of adding a light or laser.
The Generation 4 Glocks add the capability to change grip size to suit hand size. Two additional backstraps marked M (medium) and L (large) can be fitted over the standard backstrap.
Compared to the RTF (rough texture finish) previously used, the Gen4 grip surface is a bit less aggressive, with the “dots” on the sides and in the finger grooves being larger and flat-topped. Personally, I liked the RTF finish, but there were complaints the texture could be hard on hands over long training sessions. The newer design is still secure but easier on the hand than the RTF.
The Glock 21 SF is a full-size pistol chambered in .45 Automatic Colt Pistol. “Full size” is a relative term. Compared to other high-capacity .45 ACP pistols, the G21 is lightweight and average in size, but it is full-size compared to other Glocks. For concealed carry I’d rather have a 9mm or .40 S&W such as the Models 19/23 and 26/27. I could tuck away a G21 in a waistband holster from the Leather Arsenal, and in fact wore it as my CCW for a few days. Realistically, for most shooters the G21 works better as an open-carry duty sidearm or for home defense.
