So I'm a new owner of a used 1999 Para Ordnance P12-45. I didn't notice this when I bought it, but the lock back notch in the slide is a bit deformed. With full power factory ammo the slide won't lock back on an empty mag, but with low power reloads it locks on an empty mag. The notch in the slide is a bit mushroomed and bent so I'm assuming that is the problem. Can this be fixed? How would a gunsmith fix it? I'll probably need to have the slide re-coated as well, yes? Any recommendations for a gunsmith that can fix this in the Portland/Vancouver area? Any idea on what this will cost? Thanks in advance!
