I was using hollow points. I also tried some fmj from Aguilar, but had several FTFs even with multiple strikes. After about 5 I threw the rest of that box away. I really like the pistol, but it does need to be reliable. I will try to polish the feed ramp and switch to fmj as the hollow points probably aren't a good idea in that caliber anyway.
What ammuntion works best for you?
