The Glock 20 and 21 Enter The Gen 5 World

Glock moves really slowly to do new stuff. How long ago was the Glock 46 announced for a particular German contract? Heck, only this year did Glock release the Glock 47, which has served Customs and Border Patrol since 2019. Alongside that slow movement was the bringing of new guns to the Gen 5 world. In fact, Glock seems to be trimming the fat in terms of the models produced, and it’s unlikely we’ll see a 5th Gen 45 GAP Glock. What we did see at SHOT Show is the 5th Generation of the .45 ACP and 10mm Glock 21 and Glock 20.

Welcome the Glock 20 and 21 to the Next Generation

I like to imagine Glock is like a street gang that you get jumped into. I wouldn’t want to be part of the crew that jumped the big, hefty Glock 20 and Glock 21 in. These large-frame Glocks are the big boys of the Glock lineup. They’ve been fairly famous throughout their tenure. Glock as a company never gave up on the 10mm, and the Glock 21 is one of the more efficient doublestack Glocks with a capacity of 13 rounds in a flush-fitting mag.

The Gen 5 models bring all the Gen 5 features that shooters seem to love. They abandoned the finger grooves and used a better trigger, ambidextrous slide lock, the Glock Marksman barrel, and more. These guns will also be in the MOS configuration, which makes mounting optics easy. Although, make sure you use Loc Tite or even maybe an aftermarket plate. Especially with the Glock 20. I imagine the extra recoil might be hell on the MOS plates.

As usual, these guns are simple, easy to use, and the bigger bores pack a punch. While the ole 45 AC is fine, the 10mm packs a real punch and can be a very versatile round for multiple purposes. I’m excited to see the Gen 5 Glock 20. How about a quasi-single to double stack 10mm that holds ten rounds and is Glock 19-sized? A Man can dream.
