Took the max to the range on Wednesday and didn't get through one box of ammo before the slide started to lock back after every few rounds. Yep, the frame widened enough to lose control of the slide stop spring and also the TD pin access plate was just flopping around. I haven't been keeping a round count but it has roughly 500-550 (edit) rounds through it. Dropped it off at Ruger yesterday and got a call at 9 this morning to come pick it up. They replaced the frame, slide stop, spring and TD plate. Didn't notice until I got home that they never put a cleaning cloth in the box either. I measured/recorded the width of the new frame in several places and will check it after each outing. Its off to the range tomorrow to run a few boxed through it again.
