The new Sig Sauer P365 XL semi-automatic pistol builds on the popular P365 sub-compact 9mm pistol that launched in 2017. As the “XL” moniker implies, Sig has outfitted the P365 XL with a longer 3.7-inch barrel (as opposed to the P365’s 3.1-inch barrel) and the grip module accepts a flush mag that holds 12 rounds, versus the 10-round capacity of the P365. Two other improvements that come standard on the P365 XL are the flat trigger that breaks crisply at 90 degrees and a slide that is already milled to accept the Sig RomeoZero or RMSc reflex optic. We have found the original P365 pistol to be accurate, reliable, and easy to carry concealed in our field testing. Our initial impression of the P365 XL is that Sig Sauer has hit another home run with this new firearm.
The 3.7-inch barrel on the P365 XL is extremely accurate and its added length makes muzzle rise more manageable compared to the P365. The XRay3 Day/Night sights that come standard are very easy to pick up quickly and are excellent all-around sights for concealed carry. At the time of testing, we didn’t have a RomeoZero optic to mount to our P365 XL but, you can be sure we are going test one out once they are more readily available. The fact that Sig made the optic cut standard on the P365 XL shows how in tune they are to the concealed carry market and it’s great to see another manufacturer adding an optic cut as a standard feature.
