I have been using Wilson's 8 and 10 rounders for several years. No problems. Got a few CM mags that came with my pistols, no problems with those either, but the Wilson mags are eisier to work with. You gotta handle them to know what Im talking about. I bought some off brand mags when I was new to it and they sucked, stay away froms anything less than a good brand. Just buy 1 Wilson mag and you'll see what I mean.
