300 rounds through it, no problems. It is nicely broken in, comes with three mags: factory 10 round, factory 12 round and a S&W 5900 15 round mag (the P11 mag well was designed to use these), plus a Fobus holster, manual, lock and case. It is yours for $280. If you want some extra mags, I have more Kel-Tec 12 rounders (are $26 new, +S&H) you can have for $17 each. Still in sealed pouch. I also have more 15 round mags (S&W 5900 Series) which fit and work perfectly in the P11 ($32 new), for $22 each. These mags are brand new and unused.
