Bought new, cleaned it, then ran 100 various rounds through it without a hiccup. Had slide milled for micro red dot and installed a Shield OMSsc, bore sighted it, then put it back in the safe. This is an awesome $300+ premium red dot with all the bells & whistles: 8MOA, auto ON_OFF, auto brightness, clear top half gives an amazing field of view. I have too many 40 S&W pistols and arthritis is limiting my shooting, so I'm thinning them out. An excellent carry pistol: thin (less than 1 in wide), light and accurate.  Comes with OWB $75 Urban Carry LockedLeather holster, (1) 6 round (1) 7 round magazine and an extra +1 mag floor plate extension. This is an incredible package and priced agressively for a quick sale.
