The main draw of the Xtech Tactical MTX 365 +3 baseplate for your SIG SAUER P365 is the same draw of the P365 itself. In 2018 SIG hit the concealed carry market with a sledgehammer and all but killed the single stack 9mm pistol in one foul blow. Now everyone wants a micro-compact and just about everyone makes one.
Shooters and concealed carriers appreciate the small size and decent capacity the guns offers. SIG swung for the fences and knocked a grand slam with the P365.
Since then, the modular P365 has evolved steadily and has become a family of firearms with various magazine capacities. What started as 10-rounders has evolved into 12, 15, and even 17-round options.
Your standard P365 comes with two ten-round magazines, but it’s likely you’ll eventually want at least one 12-rounder…because twelve is better than ten, right? Outside of pocket carry, that additional magazine size is very much worth the squeeze.
Our drawback is the fact that a P365 magazine costs anywhere from $40 to $50. What the Xtech Tactical +3 baseplate offers is a way to convert those ten-rounders your own to 13-round magazines without breaking the bank.
Instead of buying an expensive 12-round magazine, you can spend $20 and get a simple means to extend the capacity of magazines you already own. For the same price as one SIG magazine, you can convert both your stock P365 mags to 13-rounders.
Xtech Tactical +3 Baseplate Design and Installation
XTech Tactical sent me two MTX 365 magazine extensions and I promptly installed them. The installation process isn’t complicated, but there’s more to it than just swapping baseplates. Xtech offers an easy-to-follow instructional video that makes it pretty easy to achieve.
The installed magazine extension blends in perfectly with the design of the P365. It looks like a natural extension with an identical grip texture and tone that looks a lot like a P365 grip. If aesthetics are your bag, then you won’t be disappointed.
It bears mentioning the XTech magazine extension only works for 10-round magazines. It will not work with a twelve-rounder. Additionally, the extension only allows your ten-round magazine to fit inside the base P365 grip module. It will not work with the XL grip frame and certainly not in the Macro. To be fair, ten-rounders don’t work in either of those anyway.
According to Xtech, the magazine extension will also work with the Wilson Combat aftermarket grip modules as well as the stock SIG grip module.
Adding Length to Micro-Compact Pistols
Obviously, not everyone is attracted to making their micro-compact handgun any larger than it needs to be, but those folks likely aren’t in the market for a longer 12-round magazines either. Even if you’re not looking for more rounds, the Xtech Tactical M 365 extension also makes the gun just right for those of us with larger hands.
The stock SIG ten-round magazines are just too short for my big hands. The ten-rounder I used most often had a slight grip extension installed to prevent the hanging pinky. The Xtech mag extensions fit my hand perfectly, and while larger, they don’t make a big difference to me in terms of concealment.
An alternative use will be carrying your P365 with the ten-round mag to keep the gun small, but packing a spare mag with the Xtech extension to give you three more rounds on tap.
A market certainly exists for the XL grip length grip model and the P365 length slide. SIG introduced the P365X for just those people. If that’s something you’re thinking of, the Xtech baseplates are a cheaper option than buying an XL grip module. It also provides a fairly nice grip overall.
Shooting and Reliability
I’ve had the Xtech Tactical +3 mag extensions for a couple of months now, and they’ve been a part of my daily carry since I got them. I’ve hit the range and trained weekly with these magazines and have had no problems. The magazines feed perfectly, the slide still easily locks to the rear, and they aren’t any more difficult to load than SIG’s 12-round magazines.
They eject and fall freely without issue. I live on a sandhill and in training, my magazines get full of sand. Enough so, I’m convinced they’ll always be a bit rattly. The sand hasn’t proved to be a problem, but I also do clean my magazines fairly regularly.
After a few hundred rounds of varying qualities, I’m sold on these little magazine extensions. The low price point and added capacity add to what makes the P365 already great as an everyday carry handgun. The Xtech M 365 extensions will make your gun longer, but if that’s not a concern, they’re a cost-effective means to increase capacity and grip length.
Installation is easy, and reliability isn’t an issue either. For only $20, you’re getting a made-in-America accessory that does exactly what it promises. Check it out Check out XTech’s magazine extensions.
