You can find cheaper magazine basepads for the Buckmark, but ours are "professional grade." -Solid, CNC'ed aluminum construction. -Rock-solid bolt-on attachment. -Narrow, smooth profile feels natural in the hand. -Ensures positive magazine seating. Produced at the request of "Team Gotta" (National Champion youth pistol team) and used by Jordon Castro (3rd ISR, 2017 Steel Challenge). When you order, send your magazines to us with a copy of your receipt. Address = Taylor Freelance, LLC, 2559 Woodbine Place, Bellingham, WA 98229. We'll have your basepads ready and waiting, and will do all the messy drilling/tapping for you on our CNC machines (we use a special jig and carbide tools). Buckmark magazine bases are hard enough to resist normal drill bits. Unless you have access to a machine shop, we suggest letting us do the install.
