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.

Purchased a Manual Safety installation for my Sig P320 40cal. As quoted, they milled my existing FCU and fitted factory SIG Sauer safety components and it works beautifully. Shipping was a Breese, delivered right to my door with signature. I highly recommend this company, craftsmanship, and parts. Their customer service was prompt and exceptional. You can't go wrong with ABPrototype

320 manual safety
Excellent work and speedy turnaround time. Very pleasant experience.
Service was quick, everything functions perfectly. The take down lever was extremely "stiff" but working it a complete cycle seated the fcu and works perfectly. Great job, fast turn around and much more trust in my p320 now.
P320 Manual Safety
Abprototype process was easy and fast. Was suppose to take 2 weeks, but I got my gun back in about 10 days. The work was done perfectly. The manual safety looks like it came from the factory. Thanks for what you do.
AB Prototype did a phenominal job converting my pistol to having a manual safety. If you can’t find an M17 with a manual safety and collect Mil-clones like I do, this service is invaluable. Two week turn around from the day I shipped to them was great, and I can’t find any work marks. A fantastic job, thank you!
