I own the same model. I love it. About 1400 rounds through it and it has been great. Only 7 documented Misfires due to old Winchester ammo. Otherwise no fail to load, stovepipes or whatever. The only issues I have seen is full mags need to be slammed in while reloading faster. I had a mag fall out after putting it in during an action pistol scenario. Slam them hard. It has fired anything I put through it Rem UMC, Winchester white box (only 7 misfires because of ancient, pitted brass ammo) PMC, Critical defense, Zombi Max, Speer Gold Dot, and others that I forget. ( I cannot find a consistent brand of ammo to stay with)
