Went and shot about a hundred rounds through my new warrior last weekend, and it still seems to have the same problem, but i think i have better identified the symptoms so now maybe some of you can better diagnose. I hope its not AIDS...... The slide is locking back with ammo still in the mag. The slide lock is only slightly up into the notch in which it latches into to lock the slide back. With an empty mag the lever slides completely up into the notch locking it firmly into place. When i experience my problem the corner of the slide lock lever, and the corner of the notch are just barely touching each other. Somehow the slide lock lever is flying up under recoil and barely locking the slide back with ammo still in the mag.
