While I haven't measured the thickness of the metal used in the magazine body, it seems thinner than STI/Staccato/Atlas magazines. The Prodigy mags feed lip dimensions were all over the map. (I measured the Atlas magazine feed lip dimensions and tuned my Prodigy mags the same). I know you want me to discount the springs and followers since they are consumable but considering my Atlas and Staccato have run 100% in my Staccato and Prodigy and the Prodigy mags experience stuck followers producing the dreaded saltshaker effect every now and then, I will continue to use Staccato mags for serious work.
Normally you get what you pay for in holsters. Understanding that some holster designs just don't work for some folks, a good quality leather holster will outlast the buyer.........
