If you have a magwell on your pistol, you will need to trim the base pad. I haven't had any feed problems with them in my gun. I'd guess that after you trim the base pad and the mag seats properly the other problems might disapear also.
I've got ten of these mags I use for IPSC. As far as I'm concerned they're great mags.
