Now that Sig has announced the P365X (P365 slide w/ optic cut coupled with a P365XL grip) many folks will discover just how practical this combination is. I have run the P365 with the XL grip for going on two years now and haven’t looked back as this combination just works well for me. I recently upgraded to a Zev Octane slide, added an RMSc red dot, and finished the package off with a gray, OEM XL grip module and rubber Talon Grips. I have an identically equipped P365XL but typically go with the P365 in a Dark Star Gear Hitchhiker holster (I did need to modify the holster with a cut for the optic) for edc.
I packed my gear up and headed from Seattle to Miami, FL for LaSorsa and Associates 9 day Executive Protection Agent training last month and was impressed with the performance of the home brew P365X. I was shooting the smallest handgun in the class of 16 students but my scores were right up there with those that were using full-size duty pistols. In most protection missions the need to be discrete is paramount yet you also need to have ‘enough gun’ to effectively manage deadly force encounters. The 3.1” barreled P365 is very accurate and having 12+1 in the gun before a reload with 15 more rounds is definitely sufficient for the first several seconds of such an encounter. There have been zero malfunctions through over 900 rounds fired over the life of the gun so I am confident in the reliability.
We had an opportunity to shoot duty ammo into bare, clear gelatin and the Winchester Ranger 147 gr RA9T displayed 12-13” of penetration with perfect expansion through my P365.
I just installed the boresightsolutions Razorback grip module and will update this thread once I get to wring it out some. I like how the grip resembles the Walther PPS M1 and locks into my hand during the draw and presentation.
Here’s an 8 second video of one of the basic drills from class using the P365X:
