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.

P320 Manual Safety Conversion
This is our second order and third P320 that AB Prototype has upgraded for us. That pretty much tells the story. At this point I'd rather have Alex work on my guns than Sig.

Thumb Safety
I just got back my fire control and grip module from my X-5 Legion after the upgrade to add a thumb safety. I’m very pleased with the results. I also have an M18 with a factory thumb safety and I can’t tell the difference. Great job. They advertised a 2 week turnaround but actually turned it around in just a few days. A work about customer service - I emailed them after hours with a question and they actually answered in like 5 minutes. What’s not to like about these guys? Thanks for the great upgrade and customer service!

P320 Manual Safety Conversion
AB Prototype added manual safeties to two Sig P32Os for us, an XCompact and an XCarry. We asked questions by email before the conversion and received a response within minutes. The work was completed within a couple of days. The result is perfect. Both guns look great and function flawlessly.
