Seems to be good quality... but - ProMag Smith & Wesson Shield 9mm 7 Round Pistol Magazine

Seems to be good Quality... but the magazine would not seat with the spacer in place, however, it worked fine if you removed it. This was to be primarily for range use but since I returned the item I can't comment on how well it functions. I have never had any trouble with Pro Mag prior to this minor issue.
