Manual Safety Conversion for a SIG P320 or 80% P320 Frame (Post-Upgrade Only)

*AVAILABILITY OF THIS SERVICE IS DEPENDENT ON MANUAL SAFETY PARTS*

This is a Service to convert an existing SIG P320 to manual safety. This includes the manual safety parts and grip cut, as required. We can cut factory frames or 80% frames. 

Perfect for your EDC P320 or competition!

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

The manual safety parts are exchanged for your existing SIG non-manual safety FCU parts. Grip is cut as required. No additional holes are cut or drilled!

Includes:  CNC cut your frame for the P320 Manual Safety Lever. Exchange non-safety parts with manual safety parts. Cut polymer SIG grip (factory grips only). Function test. Please add a P320 frame or 80% frame and FCU parts kit to your order if you haven't already. Lead time can be up to 2 weeks, but is often less.

Please contact us before shipping your frame (We are a licensed Firearms Dealer). All completed frames must have a serial number and must be accompanied by a copy of valid state-issued driver's license or ID card (no PO Boxes for return address). You must include the FACTORY SIG non-safety FCU parts for exchange. Conversion will not work with aftermarket trigger bars. Factory SIG trigger bar must be used. 

Return shipping charge is included, signature is required upon return.

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 Manual Safety Conversion

    Posted by James Forsythe Jr on Jan 17th 2020

    I sent an email late Saturday to AB Prototype with questions about their service to install a manual safety on my Sig Sauer P320. Within a few minutes, Alex had replied and answered all my questions. I sent another email on Sunday requesting the shipping information, thinking I wouldn’t hear anything until Monday. To my surprise, Alex again answered in a few minutes. I sent off my P320 lower on Monday, Alex sent an email in the middle of the week that he had received my lower. He explained that he would complete the work that weekend and ship back my lower on Monday. I received my lower on Thursday and the work was top notch. Alex communicated very well and exceed my expectations with his replies. Alex also exceeded my expectations by completing the service on my lower on a weekend. The turnaround time also exceeded my expectations. If you want quality work of any time, don’t hesitate to give AB Prototype and Alex a try, you won’t be sorry! Thanks Alex and AB Prototype!

    P320 manual Safety installation

    Posted by Gordon Shackelford on Dec 16th 2019

    Ab was completely helpful through out the entire process, answering questions promptly and turning the job around quickly. The safety functions perfected with a solid engagement and disengagement that inspires confidence. The striker fired P320 with a manual safety is a perfect combination which give great peace of mind in the holstering and drawing of the pistol. I recommend ab prototypes highly and will be using them again!

    Manual Safety Conversion

    Posted by Eric Peters on Nov 3rd 2019

    Install was quick and easy with the FCU and new cuts on the grips. Quick return of the items. Went straight to the range and ran about 10 magazines, and several drills. No issues with the new safety. Doing its job so far.

    Sig P320 Manual Safety Conversion

    Posted by Ron Atkins on May 26th 2019

    I am very happy with the quality of work performed, when my sig P320 had the manual safety conversion It looks like it was factory installed. The turn around time was faster than expected. All communications between AB Prototype was very professional and they did a excellent job at responding quickly. I would recommend them to anyone needing any of their high quality services.
