Let me start with that I’ve always been a steel and walnut guy who only got into ARs after retirement. I built an assortment of .45 pcc’s [both rifles and pistols] over the last 15 yrs. Olympic, CMMG and most recently a Foxtrot Mike pcc. First with a 4.5 inch upper and then a 16 inch upper. This is where I got sucked into the world of Glock as the FM lower uses G21 mags, all my other pccs use GI greasegun mags. I could invest in a used G21 [my first polymer gun] and share mags between the glock and the pcc and shoot them in the local zsa 2 gun I compete in. Last week I bought a police trade in G21 Gen3 with 3 mags. Waiting for it to show up at my lgs. As I was wanting a longslide 1911 anyway I decided to build a longslide G21 instead. Been watching a lot of G40 videos. A cool looking pistol. I also bought a Spectre Supply 6 inch slide and barrel. The barrel is advertised as being ok for lead bullets. At some point I will have the slide milled for an optic without the base plates. Photos when I actually start my build. Btw this is my first post.
Here’s my FM build.
