Help! The slide on my BHP keeps locking back early, and at the most inconvenient moments, to boot! I used it in an IPSC match tonight and it was just killing me. About every 3-5 rds it did this. I'm pretty sure it's not my off hand pushing the slide stop up. Could it be the mags? Anyone know a quick/good fix for getting this to stop? I know that 1911 stops can be dimpled to correct this problem. Is there a BHP equivalent?
