XD9 mag extended base pad

I don't know they said just +4 but it's +6 on my mag lol with the spring that comes with, just to be clear, and quick shipping too highly recommended

Required significant fitting to work

Overall these are pretty good. The only extensions I've found for the XD that actually lock into place. Two of mine worked great, but two had to have the edges filed down significantly just to allow the magazine to seat in the magwell and then also be able to easily be released with the button. Once I finally filed them down sufficiently the work well. The other drawback is that they are extremely difficult to remove once installed. Not impossible, but I have yet to find a single way to do it successfully every time. Also, the springs compacted after the first loading and significantly lost their power. The slide still locks back after the last round, but I'm nervous that any further compaction of the spring will eventually lose the lockback.

nice up grade

Didn't come with instructions but easy enough to figure out how to install. Really solid product. I did need to us a loader to get all 20rd in. I would recommend this to my friends.
