I sent it back to the manufacturer and they resprung the entire gun with heavy duty wolf springs (recoil, main, safety/ slide lock, firing pin, and leaf). They also went the extra mile and polished the feed ramp, chamber, inside of the slide lock, and lapped the slide/ frame. And they had it back to me in a week. I was dumbfounded they did all this, considering it was a $700 RIA.
But the heavy duty springs are what really fixed the problem for me. Full house 10 was battering the frame and bouncing the slide lock up. The gun still functions great on soft ball Armscor all the way up to Underwood.
