Maybe I'm the last guy to do this, but I recently saw the wisdom of it: (1) Remove barrel from gun (2) Drop each round of your EDC ammo in the breech end to make sure it seats properly and doesn't get hung up from a case being bulged. I began doing this when I had a feeding issue with some brand-name factory personal defense ammo. Just by random chance, the top round of the one mag I had inserted wouldn't feed correctly. I thought it was a generic feeding issue (bullet getting hung up on barrel ramp, etc.), but when I disassembled the gun and tried to seat THAT particular round in the barrel, it wouldn't seat due to case bulging. If that round been further down in the mag, I could have had a major hang-up at an inopportune time. So, now I'm in the habit of testing every round of carry ammo in the disassembled barrel before it goes into a mag. I'm surprised that I've never heard of anyone doing this basic safety/reliability check, and no one has ever recommended it to me in my 15 years of handgun shooting. Like I said, maybe I'm the last guy to do this, but I thought I'd recommend it if it's not part of your regular routine with a new box of your EDC ammo. It takes a few extra minutes, but well worth the peace of mind, IMO.
