Well, to be perfectly honest, the only mags I have found worth the money are the 10 rds made by Pro Mag. Sold by fourfourmag.com. I have a 40 PMI that is crap and what I am told is that USA Mags are no better. I'd rather have a reliable 10 than an unreliable 100. The first 2 are all that count anyhow--then you have moving targets (those that are able to run). Besides, I can carry a 10 in a shirt pocket. Damn those beer cans anyhow!!!:usa:
