I haven't had luck with the high cap mags. The 50's wouldn't feed at all and the 25's weren't much better. Ruger needs to make some high quality hi-caps.

I've got a couple of 30 round mags for mine that have worked just fine. No jams or failures to feed, yet. I think they're ProMags, but, I'll have to check when I get home later.
