So I'm running powder coated 147 grain cast through a Glock 17 with a Gemtech Luna 45 suppressor. After 9 different loads with 5 different powders. it just quite fully eject. My question is does anyone with experience, think a reduced recoil spring would help? Or any other constructive conversation would be welcome. Side bar, I had no problem developing a load for a 1911.Thanks in advance for any thoughts. jeepyj
