The P365X and XL use the same 12-round grip frame. The length of the slide is different. the P365X has the shorter, standard P365 slide, while the P365XL has a longer slide and barrel. Both are standardly equipped for optics.

Good evening to you!! The P365X and P365XL use a 12 round grip frame. The P365 and P365X use the standard short slide found on the P365. Hope this helps. Have a good rest of your day.

P365, P365 X, P365XL, P365X Macro, P365X Macro Comp are the models (other than Fuse, Legion).

You are mostly correct, but the P365X and XL share the same 12-round grip frame. The main difference is the slide length: the P365X has the shorter, standard P365 slide, while the P365XL has a longer slide and barrel. Both are standardly equipped for optics.

Key Differences Breakdown:
P365X: Short slide (same as standard P365) + 12-round grip frame.
P365XL: Long slide + 12-round grip frame.
Magazines: Both use the same 12-round (or 15/17-round) magazines.

Hi Tim and welcome. You are correct. The SIG Sauer P365X and P365XL both feature the same, larger 12-round grip module and flat trigger, but differ in slide/barrel length. The P365X pairs this grip with a compact 3.1-inch slide, making it better for concealment, while the P365XL uses a longer 3.7-inch slide, offering better accuracy, reduced recoil, and a longer sight radius. <>Key Differences:
Slide/Barrel: P365X has a 3.1-inch barrel; P365XL has a 3.7-inch barrel.
Concealment vs. Control: The X is easier to conceal; the XL provides better recoil management and faster follow-up shots.
Sight Radius: The XL has a longer sight radius, aiding accuracy.
Optics: Both are optic-ready, but the XL often allows for a slightly better optic fit depending on the specific model generation.


+4
Both models feature a 12+1 capacity (with 15-rounders available) and use the same grip, making them both highly ergonomic for shooters with larger hands compared to the original P365. The choice between them depends on whether you prioritize maximum concealability (X) or improved shootability (XL). Cheers, stay safe and enjoy!

Hi Tim, There are two basic slide length families in the P365 lineup:
“Standard” P365 length (P365 & P365X)
“XL” / Macro length (P365XL & X-Macro slides)
.
Original P365 Slide
The original P365 slide is the shortest of the family.
Designed around 10-round flush and 10/12-round extended mags
Compatible with:
P365 grip module
P365X grip module
You can put a standard-length P365 slide on either a P365 or P365X grip module (same dust cover length).
.
P365X Slide
The P365X slide is the same overall length as the original P365 slide and is often optics-ready from the factory.
.
P365XL Slide
The P365XL slide is longer and uses a different recoil system suited to the XL length.
Compatible with:
P365XL grip module
P365X or P365 grip modules (mechanically possible, but the dust cover will sit shorter than the slide, creating an overhang)
.
X-Macro Slides
X-Macro slides live in the same general length family as XL slides, but may include:
Comp/port-style muzzle designs
Different front sight positions
Optic-ready cuts as standard
From a pure fit standpoint, X-Macro slides are built around the X-Macro grip module, but can be used on other grip modules with caveats (holster fit, muzzle/comp exposure, etc.).

Stay safe & have a great day!
