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 (X-Ten Carry Comp cannot be converted due to the slide width). 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.

320 manual conversion
I failed to mention in my previous review, That from the day I mailed the FCU to Alex I had it back on the sixth day. Less than a week.

320 m/s conversion
Alex and the team at AB Prototype are the real deal. Alex should be the business model for customer service. He returns calls quickly and is patient when, we ask our many questions. The conversion to add the manual safety is flawless. Mine works as it was designed. The m/s cut on the Wilson Combat grip looks like Bill did it himself. If you have smaller hands, I would definitely recommend the Wilson grip module. The workmanship is totally professional. If you are reading this review, you are obviously considering having the conversion done. Go ahead, you will not be disappointed. Sig, if you are reading this review, you might add AB Prototype to your team. Something wrong when they offer a service to Sig 320 owners that you do not.. If the military wants manual safety’s on their 320s, we ex military and civilians want the same option. Great work Alex. You will be recommended to any Sig 320 owners that I come across.

P320 Manual Safety Conversion
Just received my upgraded P320 lowers. On both, the safety is a crisp on/off without any mushiness. Furthermore, I can't detect any difference in trigger pull compared to before the conversion. It's everything I hoped for, and definitely worth the price!
