Ordered six (6) RWB magazines for a glock 9mm but upon opening the first package it was so tight the mag could NOT even be forced into the grip frame. Opened 2 more and they were all too tight to insert into the pistol. By the time I called Classic Firearms they informed me that the return window had passed and they would not take the item back and provide a refund. FIRST, Save yourself the hassle of working with a vendor such as CLASSIC FIREARMS and order your stuff from reputable online dealers. SECOND, avoid the RWD mags as the don't work in the Glock frames anyway. The money I saved on getting this cheaper option just went into the trash....share this with your shooting buddies! RWB mags and CLASSIC FIREARMS are both low rung companies - avoid like the PLAGUE !!!!!
