I have the Rami P with the stainless slide that I carry a lot!so far no sign of the dreaded bulge on the frame! I have been having problems using the hi capacity mags on it. Feeding is not reliable as at times the bullet gets stuck in the mag and won't feed or it does not fully seats! I have changed the mag springs twice and still the same. It has no problem with regular mags which I carry it with and never did this. I have two high capacity mags that does the same thing. I cleaned, put new springs and still happens a lot! Any suggestions? Thanks!
