Questions & Answers
Is this compatible with the Sig Sauer Model: 320CA-9-M18-MS-CA? Expert Answer

Yes, this SIG SAUER P320 Compact/Carry/Full Size Slide Assembly would be compatible with the CA compliant P320 M18. You will also be able to use your original M18 barrel and recoil assembly as both are not included with this slide.

Does this come with internals except barrel? Expert Answer

Yes, the Sig Sauer P320 3.9" Slide Assembly is a complete slide that only requires the barrel and recoil assembly to function.

This is a compact slide, not full, not carry by Kyle, Verified Owner, June 10, 2024
Luckily the 3.9” slide is what I needed, but not sure why all 3 slides are listed in the title.

P320 Upper Slide by cadhoops, Verified Owner, March 12, 2024
Needed to replace my P320 slide to mount a red dot. This version was easily installed and now I can attach a red dot.
