Only 150 rounds through it. Tested w the sig ammo and a full box of the self defense loads and shoots perfect. 15 & 10 round mags. Comes w 200 rounds sig ammo and 50 of the hollow point self defense loads. 

listed as striker fire but these are internal hammer fired  so easy to shoot. 

Willing to trade for a .22lr pistol or rifle as well. Let me know is if you have any questions. Thanks!
