Many find the P365X & P365XL to be just a little too short. For this reason many search for a magazine extension that doesn’t exist for it. The reason? We have a patent on the best solution for magazine extensions when the rails at the bottom of the magazine face inward. Why don’t we make an extension for the P365X or P365XL?
- The magazine rails stand off from the magazine making durability for drop tests more of a challenge vs. the 10rd magazines. Impossible, no, but much less durable.
- Any extension to the 12 round P365X / P365 XL Magazines would end up about the length of the 17rd magazines but only 15 rounds.
For all the above reasons and the fact Sig on their base plate does not support the back of the magazine, the XTech MAG-ADAPT S365-17xl is the best available Sig Sauer P365-XL mag sleeve from XTech Tactical. This top-rated handgun extension offers better performance and control while adding rounds to your shooting activities. Gun enthusiasts who need extra magazine capacity for personal defense or other uses will enjoy the added stability of the slightly longer grip.
Adding more rounds in your hand for ready use with only a slight increase in size is ideal for concealed carry or other holstering applications. XTech sleeves significantly upgrade the already wildly popular Sig Sauer P365 9MM pistol with X/XL frame sizes. Shooters with larger hands or those needing better precision control know this Sig P365-X pinky extension offers considerable benefits for its slight size. Many like to think of it as a 17 round mag conversion for the P365 X/XL.
Like all XTech Tactical magazine sleeves, the MAG-ADAPT S365-17xl is made in the USA and easily installed with no special tools. Slide it into place over the existing magazine and enjoy better performance in various tactical situations.
This exceptional 17-round magazine sleeve is legal in all markets and is also offered with a factory 17-round magazine here: https://www.xtechtactical.com/product/sig-sauer-p365-factory-9mm-17-round-magazine-w-mag-adapt-s365xl/

Fits excellent and gives it a nice macro style look with the original XL or X slide while filling in that lower back end of the magazine for a more full finished look. Honestly is 4.8 stars but I think if it had a similar texture to the Sigs texture for a matching finish would have pushed it to that 5 star.
