Great piece of kit

I picked up one of these beauts for my P320 X-Compact. There's a very small gap between the mag bottom lip and the slot in the extension but this seems to be purely cosmetic. It doesn't rattle or affect performance. It functions flawlessly on stock 15 round mags and that includes hollow points such as HST 124gr and V-Crown. You would think it's difficult to carry due to the size of the base but this isn't the case. The 15round mags were difficult to draw from my mag pouch. The size and the side cutouts on this extension actually make it much easier to draw from my particular mag pouch. It also conceals surprisingly well on the 15 round mags and doesn't dig into your side. The only downside is the price. Altogether I think it's an awesome addition to the setup. It functions flawlessly and looks great doing it.
