Manual Safety Conversion for a SIG Sauer P320

This is a SERVICE to convert your existing SIG P320 to manual safety (works for most Gen 1, post-upgrade, AXG, X-Ten, Wilson Combat, ZEV, etc). This service includes SIG Sauer OEM manual safety parts and grip cut, as required. We can cut factory frames. 

Perfect for your EDC P320 or competition!

We precision cut the manual safety pocket in ANY P320 FCU in 9mm, 40S&W, 357SIG, 10mm or 45ACP to exact SIG Sauer specifications. Each frame is tested for fit and function.

The SIG manual safety parts are exchanged for your existing non-manual safety FCU parts. Grip is cut as required.

Includes: CNC machine your FCU for the P320 Manual Safety Lever. Exchange non-safety parts with manual safety parts. Cut polymer SIG P320 grip (SIG, Wilson Combat and other grips ok, Polymer80 requires additional customer modifications, AXG or Icarus aluminum grip +$10, inserts will not be cut). Function test. Lead time can be up to 2 weeks, but is often less.

We will reply to your order confirmation with shipping instructions. We are a licensed firearms manufacturer and can receive and return firearms directly to customers' residence address only. All completed FCUs must have a serial number and must be accompanied by a copy of valid state-issued driver's license, CCW or ID card (no PO Boxes for return address). Conversion may not work with all aftermarket trigger bars such as the standard forward-set Apex trigger bar (manual safety version will work).

Shipping charges cover return shipping only, signature is required upon return. When shipping please do not include cases, manuals, slides, optics, etc. unless specifically necessary for other services.

FCU Parts, Barrel, Slide, Grip, Magazines, etc. are obviously NOT INCLUDED.

PLEASE NOTE: AB Prototype modifications to your frame are not authorized by SIG Sauer or JSD Supply. Any modifications to these frames will most likely void any existing manufacturer warranty. AB Prototype does not provide any additional warranty, neither expressed nor implied. We only guarantee fit and function of the manual safety lever on completed frames.

    P320 XCompact Manual Safety Conversion

    F.S from CO. (P320 Manual Safety Conversion). Once again I am VERY PLEASED to report that the guys at AB Prototype have suprassed all my expectations on the quality of their work on the conversion/adding a manual safety to my P320 X-Compact pistol. The quality of their work is flawsless and rivals the best in the industry. My new manual safety is indistinguishable from the factory manual safeties on my P320-M17/18. Turnaround time was awesome...left my house a Mon and returned on Sat - 6 DAYS TOTAL!! My best comment would be - if I had any additional P320 X-Compacts that needed a manual safety added...I would send them all to AB Prototype. If you are considering this conversion - DO NOT DELAY - send it off today...if you don't...you are only punishing yourself!!!! I rate them as 15+ stars.....

    As close to OEM as you can get. Worth the money. Looks and functions as if it was done by SIG themselves.
