Had this gun for a year...gun is spick and span clean...the flap cover that goes over the primer is wanting to hang after a shot...and this is with it clean before I shoot...never had this problem till this week...I took it apart and cleanned it really well just to double check it...I am shooting blackhorn 209 and CCI M 209. I am talking clean gun first shot....wants to hang and not open...beat it get it open and clean it real good...shoot again and same thing....This is the only down fall to the gun...I have found it to be a real shooter with about any ammo choice I have put in it though...I sure like the optimas the more I look at them!
