Disappointed! - Volquartsen Firearms Firearms Laminated Grips for MK IV

I was hesitant to purchase this grip because of cost but they looked nice and they were target. After i installed it my magazine's would not lock in. After close inspection volquartsen never removed enough material to let magazine's work. Glad i use to be a cabinet maker because i had to plow out over an 1/8 inch of material around the bottom opening with a sharp chisel to get them to work. Over priced junk, and Volquartsen thinks they're professional. Look elsewhere!
