I have had it for about three weeks now and have not experiences any problems. 800 rounds of mixed ammo, ball, HP's Bonded, 124 -147 grain. Everything fed, fired and ejected as expected. Ejected brass ended up in a neat pile about three feet to the right. The only change I made was I swapped the factory sights for Sevigny Carry sights. Perhaps the extra weight of the steel sights help stabilize the pistol.
