Purchased my first Shield 45 from Kentucky Gun Co. in October. When I picked it up from LGS, the mags looked new. I purchased a 3 pack of 7 rd. mags from Quantico Tactical, and they looked new. Picked up my second Shield 45 last week that was shipped from Palmetto. The mags had the black stripe on the follower and the gun was heavily oiled unlike my first one. All mags have functioned flawlessly so far, as have both guns.
