This kit includes a new +20% extra power spring and a hardened steel locking plate. These are the only extensions for the XD45 that have locking a plate to keep the extension from popping off your magazine as it hits the ground. The spring is very high quality and are custom made to fit exactly like factory, yet give you the extra force required for proper feeding.
Note: If this product is used with the XD(m) 45ACP model, slight modification to the extension itself may be required for proper fitting.
With the help of a UpLULA Magazine Loader, we were able to fit three extra rounds of 45ACP into a 13 round magazine, giving you a capacity of 16+1. Not too bad for a 45ACP!
