Great, but what if the SHTF and you did not have your "broken in" gun
It's not a matter of being broken in, per se, but well tested and proven to be reliable. That's probably what you meant, but I want to be explicit, that's all.
and you could run into a gun store and get something new off the shelf (Autopistols please, many would grab other items I'm sure) what would you grab to use out of the box?
In the spirit of trying to answer the original question, I'd pick one to use but I still wouldn't
trust my life with it.
Which one? I'll put in a vote for the
S&W M&P, since it was my favorite when I went shopping for my first handgun.
I don't know whether it's more or less reliable out of the box than Glocks, HKs, SIGs, and others, but they all seem about the same to me. Every one of them went bang every time when I tried them, despite being filthy rental guns, while .22 LR autopistols kept jamming on me (the RSO thought I was limp-wristing the .22s
, but then they jammed on him, too
). My sister, who treats everything gingerly despite being fairly strong, managed to limp-wrist a Glock 17 a couple of times, causing FTEs (never happened to me, and I know it doesn't happen so easily with every individual Glock), but the others kept chugging along. I actually tried to get my own M&P to fail while testing it (loading only a single cartridge at a time for safety's sake, although it never flew out of my hand
) but it wouldn't. There's one more tiny data point for you.
