Stock Glock with factory ammo, can't argue with that. At a Glock Demo Day at the LGS I inspected a G48, did a quick field strip and the innards were literally caked with residue. Like wow, they are touring this gun for sales purposes and they've never cleaned it. I put 10 rounds through it no trouble but that's trivial. Six months later I wouldn't be surprised if it's still on the demo circuit and they still haven't cleaned it.
Semi autos have gotten so reliable and have such an advantage in size vs. capacity that I consider revolvers obsolescent as a CCW.
