The guns I feed are several 9mm Glocks and a G30 and G21. I did some searching, and it sounds like his <230gr .45 bullets may not work so well in the G30. I've become a fan of lighter bullets in the .45 Glocks (mostly because when I shoot pins with them, I want velocity, but not recoil). The Precision 200gr and PD 185gr JHP both seem to work in both guns. Wanna kill these ads? We can help!
