ProMag anything is not a good plan - unless you want lots of malfunciton clearance drills.
While they may work for a while, they simply do not hold up.
Remember the rule: Buy only factory mags or from MecGar for most pistols. The exceptions are MDS (Beretta), Metalform (Colt, Ruger 1911s), Wilson (1911), McCormick Power Mags (1911), and ACT Mags (Novak, RIA and S&W's 1911s - and ACT Mags get somewhat mixed reviews).
