To me the LCP is a gun that you will probably run one thousand rounds through in the next fifteen or twenty years. For something to run a thousand per month through, I'll get something that is a LOT bigger, a LOT heavier and a WHOLE LOT more expensive.
I'm not real sure about the "whole lot more expensive" part. I would imagine a sub 400 dollar P95 would run as long as a Glock. For that matter, Glocks ain't all THAT expensive. I have a P90 that is flawless, gave about 300 for it 17 years ago, and I don't reckon I could wear it out in 3 lifetimes.
I've got a Kel Tec P11 still running strong after 11K+ rounds count in the last dozen years. It's never failed me. I carry it constantly, though I don't shoot it as much as I once did now days. But, then, I have a 380 that I've had longer, bet it ain't had 1K fired though in its lifetime. LOL Well, maybe between 1 and 2K, but no more. I've carried it a lot, but not fired it a lot. So you sure have a point there. I'm set up for 9x19 on a Dillon Square Deal progressive, though, and load .380 on a single stage press. I don't particularly like reloading .380, too hard on the fingers and eyes. LOL 9x19 ain't a lot better, but on the progressive, it don't take as many steps. I don't really like shooting that .380 anyway, not all that accurate, and setting up for it on one of my progressives just seems like a waste of money. In autos, my 9s and my .45 are my favorite range guns, well, other than .22. My new to me Ruger Mk 2 has sort of taken over. I love shootin' that thing.
