This kit include a new +20% extra power spring and a hardened steel locking plate and holds an extra 3 rounds. These are the only extensions for the XD45 and XDM45 and the new XD MOD.2 that have locking plates to keep them from popping off your mags. The springs are very high quality and are custom made to fit exactly like OE in the XD45acp mag body. This is a +3 extension that does not prevent the slide from locking open after the last round has been fired.
NOTE: When using with the 10MM models, you will need to use your factory magazine spring.
