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.
DOES NOT FIT THE XDM ELITE.
