My two Pro-mag magazines for a P225 ( P-6) are a disappointment. They wouldn't load all 8 rounds of 9mm, and after they're empty, they don't catch the slide. I opened them up, and trimmed off enough spring to allow me to load 8 rounds, but have no FIX for the empty magazine problem. I DID find some REAL SIG magazines on E-bay for $30 each, and bought a pair. They were, in fact, quite good, one looked like it had never had a round in it.
