These units replace the .45ACP 10 round magazine base plate. They do not alter the capacity of the magazine and provide better comfort by adding approximately 1/2 inch of gripping surface. YA BABY!
Key Benefits
BRAND NEW PEARCE 2008 release...We have been wanting this for months... These units blend with the contours and texture of the handgun and have a factory appearance.
They are made from High Impact Polymer and withstand drop tests and temperatures from -20 F to 350 F.
They provide control and comfort without sacrificing conceal ability.Even though they are longer THEY are still shorter then the 13 rounder. We will post comparision pics soon

These fit the XD Compact .45ACP ONLY. I Guess you could put it on a .45ACP 13 rounder IF you have HUGE hands. It could look kind of COOL on a Tactical... Hum...
Great for those of you who conceal carry.
