Sig Sauer P320 Pro-Cut Slide Assembly Optic Ready Nitron Black

A: Hi Samuel and welcome. Yes, a standard full-size Sig Sauer P320 Pro-Cut slide assembly will physically fit on a P320-M17 fire control unit (FCU) and grip module, but you will lose the M17's manual safety cutout unless you modify your grip module, and the optic cut style differs. Cheers and stay safe!

A: Yes, it will fit your SIG Sauer M17. Because the military and civilian M17 is built natively on the full-size P320 platform with a standard 4.7-inch barrel, this slide is fully cross-compatible. Key Details & Compatibility Barrel and Recoil Spring: This slide is designed exactly for full-size 4.7-inch non-threaded barrels or 5.5-inch threaded barrels. You can drop your factory M17 barrel and recoil spring assembly straight into this slide. Optics Footprint: Upgrading to the Pro-Cut slide gives you a removable optics plate with an R2/DeltaPoint Pro footprint. It will directly host optics like the ROMEO1-PRO, ROMEO2, or Leupold DeltaPoint Pro. Sights: It comes pre-installed with XRAY3 day/night suppressor-height sights, which allow you to co-witness if you choose to mount a red dot. Safety Cut Notice: If your M17 features a manual safety toggle on the frame, please note that this slide is universally compatible with both manual safety and non-manual safety P320 Fire Control Units (FCUs)
