Aluminum XDM 9/40 OPEN Magwell
XDM 9/40 OPEN magwells are CNC machined from Aluminum.
This magwell was specifically designed for USPSA OPEN and
LIMITED divisions. The OPEN magwell has a HUGE opening but
is also ergonomically designed not to interfere with your
grip. This is for full sized XDM 9mm and 40S&W frames only.
The unique attachment method requires that you grind the
backstrap even with the top of the magwell opening. It
will work with the #1 backstrap with the basic backstrap
modification also. For use with the #3 backstrap if you
grind the back of the insert to fit the profile of the
magwell. Does NOT fit with factory base pads, modification
required to fit.
