Frequently Asked Questions

Are Sig P365 and P365XL slides interchangeable?
No. While they look similar, the XL slide is longer and fits only XL frames or grip modules. Standard P365 slides work only with P365 lowers.

Will I need a gunsmith to install a new slide?
Not usually. These are drop-in parts designed to work with factory internals. However, proper installation and function checks are always recommended.

Do I need to buy a new barrel or recoil spring?
Only if your upgraded slide specifies a unique length or compatibility. Otherwise, most slides are compatible with standard OEM parts.
