P320 Manual Safety Conversion

Alex was fantastic. Responsive to my pre order questions was exceptional. Turnaround was less than 10 days (door-to-door). And the work was outstanding; fit and function is impeccable. Highly recommend AB Prototype and Alex.

I couldn't be happier with my new safety. It looks like it came from the manufacturer. I got my frame back in 8 days. You just can't beat that.

Unfortunately the p320 has an inherent design flaw that makes carrying chambered dangerous. I am not referring to the drop issues but rather how easily the internal safeties are disengaged with the slightest of trigger movement. Many situations can cause this to occur and issues can arise from this. This is why other striker fired pistols have trigger or grip safeties. The only safe bet for a p320 (other then carried without a round chambered) is a manual safety but this modification is not offered by SIG. Oh well, I would rather void my warranty then risk potential tragedy. Alex’s work is clean and was done quickly. I am very pleased with the results of his work on my firearm and highly recommend all p320 users have a manual safety on their firearm.

This is the second one that Alex has done for me and I am just thrilled with it. Before I had this done to my 2P320 compacts I was afraid to load the guns except at the shooting range because they both had a 4 pound trigger pull and I was a captain in the Marine Corps and have been shooting for almost 70 years so it is not like I was an inexperienced shooter. This I feel makes them much safer and it only takes a fraction of a second to flick off the safety.

As an old marine who always carried a 45 with a safety in places like Viet Nam I had to have a safety on my P320 and I couldn't be happier with the results. It is absolutely perfect probably because it was designed by the US Military who wanted their people to be safe and ready for action in a nano second. Alex at AB Prototype did a superb job on the conversion and it looks like it was done at the factory. I like it so well that I just sent my other P320 compact to AB Prototype for the conversion.

After reading about the drop tests and accidental discharge issues with the original P320, even though I had the fixed version, I still wanted to make sure I wasn't going to have any issues with a weapon that would be carried daily. I could have purchased a different pistol, however I found Alex and AB Prototype. The positive reviews convinced me, and so I sent my sig from NY to CA for retrofitting. Alex was great, and we had some initial delivery issues due to my FFL messing up the transfer address, but we got it sorted. Throughout the process, Alex was on top of it and kept me updated. The conversion was done in less than a week, and I had my P320 back. The work looks factory, and the safety feels great. It engages and disengages solidly, and gives me a little more peace of mind when I am carrying. Great work! No hesitation in recommending AB Prototype to anyone looking for similar services.

Wanted to add the manual safety to my X5 Legion. All my other handguns have them. They did a great job at installing the manual safety. Supplied the replacement parts and all. Absolutely "Zero" complaints about AB and the service.

This company is first class... they communicate very well and the work done was fast and of very high quality. I wish they would move to a more gun friendly state! Missouri would welcome them with open arms.

AB Prototype Reply - Thank you!!!

The Manuel safety appears and functions just as if it were installed at the factory by Sig. According to Alex, the owner, he uses all new parts that he obtains from Sig Sauer. I was told the work would take 1-2 weeks and it was completed in 1 week. I am very pleased with the results and with Abprototype. Highly Recommended.
