A few years ago, I switched from 9mm EDC to .45 acp EDC (10+1). I took the new pistol to a local indoor range and asked for two boxes of HP ammo. The guy looked at me like I had 2 heads, wondering why I would shoot these as a round at a range. I told him I needed to determine if the round would feed properly, fire cleanly, and eject properly. "OH". The first ammo stovepiped quite a bit in those 20 rounds and the Hornady Critical Defense was flawless and now resides in my mags. Gotta see what food your weapon likes/dislikes. I think for every 200 or so 'target' ammo I run, I then run a box (20) of self defense ammo. A tad expensive, but I want to know I can still rely on the ammo I am running.
