Stabilize your full-size Walther PDP! Adding a brass backstrap adds weight to the lower part of the frame. That weight counteracts the "top-heavy" feel of polymer autos, and calms perceived recoil. In our experience heavy backstraps also improve the "feel" of the gun -- especially when speed reloading. The pistol rolls into position smoother and more predictably -- and doesn't feel like it's trying to flip out of your hand. - CNC Machined from bar stock - Works with a to-be-released TF magwell - High-traction checkering stabilizes the gun in your hand - Adds 3+ ounces over stock NOTE: IDPA shooters should read their rules carefully. IDPA shooters will likely be able to use the aluminum variant only due to IDPA's past restrictions on "brass grips."
