These are so much more solid than the factory 12 round mag grip extensions. Super easy to install and a no brainer for a better grip and more capacity on the standard p365.

Installation was pretty much straight for for the mag extension, spring etc. Loading without the UpLULA would be tough for my wife. She liked the shape and produced better groups with the extended mag. A fully loaded magazine was a bit thougher to get locked into frame of the Sig 365

Works well. A little tricky to install but the video is useful.

After installing the 3+ magazine extension I ran a couple through the 365. I liked the new feel of the grip so much I ordered 2 more. I highly recommend this product.

Very nice product. I installed the +3 extender on one of my 10-round mags for use at the range. The fit and finish are excellent. I did use a pair of pliers to squeeze the extender into the mag, as suggested. That worked very well. Now I really like the feel of the extended grip. There was no problem loading rounds into the mag afterward. As is my standard practice, I used silicone spray in the mag and then wiped it before installing the spring.

5 stars. Converted my 10 round factory mags. Much cheaper than buying the larger sig mag. Take your time when making the conversion. Paper instructions are not the best. Watch the YouTube video. The first one took some time and frustration took over. After getting the first mag figured out and done, the second mag didn’t take more than three minutes. Quality product. Makes a huge difference in my grip on the pistol. I highly recommend XTech Tactical and this product

Converted my 10-round magazines to get more use out of them. On installation one of the new spring sets did not set just right and the magazine would not load 13 rounds. Unloaded, disassembled, checked, and reassembled the magazine and it now loads 13 rounds properly. Overall a good product. I will update you when I have a few hundred rounds through these magazines.

Definitely one of the better polymer 365 extensions.
