Glocks Fuddy Five Lurches into the 2020s

Glock first announced the .45 ACP-caliber G21 alongside the 10mm G20 and .40 S&W caliber G22 back in 1990, in a host of caliber changes that offered more than the company’s 9mm initial offerings– the G17 and G19. At introduction these were 2nd Generation guns, a series only gently updated from the company’s original debut in the mid-1980s.

I’ve been fooling with the G21 off and on for almost 30 years. My first was a Gen 2 AAZ-serialized G21 that I picked up in 1994, just as the federal AWB and magazine cap kicked in that chopped the standard mag capacity from 13 rounds to just 10. I kept that tough-as-nails .45 through Hurricane Katrina, during which and immediately after it was never far away, and only passed it on to its current owner in 2006, downgrading to a 9mm as my everyday carry.

My first G21, a Gen 2 model, is seen here in a low-res circa-2005 image. It worked when I picked it up 11 years before, ran everything I fed it in the interlude, and it is likely still working wherever it is today. Note back then they didn’t even have thumb grooves or an accessory rail.

Then came the Gen 3 Sport/Service models in 1997, which brought with them recessed thumb rests, finger grooves molded into the frame, and, eventually, an accessory rail.

The Gen 4 G21 arrived in 2011 with the company’s improved RTF-4 texture, interchangeable frame back straps, a reversible enlarged magazine catch, a dual recoil spring assembly, and a new – some would say improved – trigger

And since then, the G21 has been frozen in time, locked in 2011. In the meantime, the company introduced their 5th Generation guns – but only in 9mm (G17, G19, G19X, G26, G34 and G45), .40 S&W (G22, G23 and G27) and .22 LR (G44).

Now, Glock finally reached back and brought the old “large frame” 10mm and .45 full-sized pistols into the present.

Importantly, it is the first time the G21 is optics-ready, in addition to other Gen 5 enhancements that are long overdue.
