1911 and GLOCK®-Compatible Build Kits for your 80% frame.
Find every popular build kit for your 80% GLOCK®-compatible (p80) frame, your newly-fabricated aluminum 1911 frame, or even your 80% MUP-1 Sig P320 chassis! Kits are available for most popular GLOCK® models. All 1911 and P320 kits are compatible with fabricated 80% frames, and factory-produced firearms.
Once you've finished your 80% frame, you'll need a GLOCK® kit - like the ones above - to assemble your frame. Each kit includes the parts for your frame's "upper", or slide, and its "lower" or frame. That means you're getting a complete slide assembly and all frame parts, pins, and springs! All you'll need to hit the range (after fabrication and assembly, of course) is a magazine and some iron sights.
Enter the new-and-improved 80% aluminum 1911 frame! Made by Stealth Arms, these frames are compatible with .45 ACP and 9mm 1911 and Commander builds, making them the perfect way to own an upgraded, lightweight 1911 for a fraction of the price of those "top-tier" factory guns.
All you need to complete your finished 1911 frame's assembly after fabrication is a parts kit from above! Each 1911 build kit includes a full frame parts kit - all pins and springs are included - and a full slide assembly with a match-grade barrel, cut with a target crown. Kits include black diamond-etched grips for comfort and control, plus nitride-treated slide that provides a sleek, black look with an incredibly tough finish. Novak fixed sights are included!
Sig Sauer® introduced the modular P320 to fanfare. So, it only makes sense that this easy-to-upgrade handgun got the proper 80% treatment. Now you can build one truly custom, from scratch, in any configuration you want after you finish your MUP-1 insert! Using a fabricated MUP-1 insert, you can assemble a P320-compatible platform in the popular Carry, Full-Size, or Compact configuration.
