The SIG Sauer P365-XL is a micro-compact 9mm pistol designed for everyday carry. It offers a balance of concealability and shootability with its extended grip and slide length. We added this model to our catalog in summer 2025, and it has proven to be a reliable seller with consistently positive customer feedback. The finish quality on the batch we received was excellent, with no visible tooling marks.

Your Questions Answered
Does the P365-XL use the same magazines as the standard P365?
Yes. The P365-XL is compatible with all SIG P365 series magazines. The 12-round magazine ships flush with the XL grip. Standard 10-round P365 magazines will fit but will have a small gap at the base.
Is the slide cut for a specific red dot footprint?
The slide is cut for the SIG Sauer ROMEOZero footprint. For other popular micro red dots like the Holosun 407K/507K, you will need an adapter plate, which are widely available.
