Nearly 2000 rounds, @ 6 malfs, mostly early on. Comes with one mag.
I find I choose ammo more on availability and cost rather than function. The LCP is NOT finicky.
Do avoid the Herter's brand from Cabelas. Got a squib load of that, lucky it was close to the chamber so the LCP didn't go into battery....
I have also had malfunctions in several different types of pistols with Cor-Bon, and also HPR, which is a new Arizona-based brand.
