lets just bring back the .224 boz. 10mm necked down I believe
Yea I got that 5.7 thing wrong, I think it was case diameter.
Okay so here's what I found out.
38 super oal-1.28in
22tcm- 1.265
45acp- 1.275
9mm- 1.150
Lone wolf did make 38 super glock barrels for Glock 20's, can't find them on their website now. So a Glock 20 conversion barrel and new extractor sounds like it would work
I read on Wiki (I know, I know) that the .224 BOZ is being revamped for a necked down 9MM for use with drop in conversion barrels. That's be sick. I so badly want a Glock 5.7 - style pistol : (
