P365 FCU
Fantastic product from a fantastic company!!!

Gets it done!
When I ordered this I thought I was getting a "Sig" branded FCU. What I received was in an AB Prototyping package. However, it looks just like the Sigs I already have. So I'm not sure of the origin. Having said that, its a perfect fit for my grip module and slide. It also seems to function perfectly. I haven't yet had a chance to fire it, but function testing is indeed perfect.

Been tough to find this...
I'd been in search of this (P365 FCU, Black, Flat trigger) for some time, and with no success. My original P365 was revamped as an SAS, leaving me with almost a whole other P365 absent the FCU. Typical Sig quality, easy installation after a quick clean, smooth action and consistent trigger pull weight.

AB Prototype P365 Standalone FCU
Outstanding build quality and value at an affordable price. Great for those custom builds!

Solid Product
I ordered all the parts and pieces for a P365XL from various vendors. AB Prototype shipped this FCU to my local FFL quickly. In fact, it’s the first piece to arrive. It’s solid and ready to be put together. These guys are one of the few places I saw the P365 FCU in stock and hands down, the best price! Don’t sleep on it if it’s available.

Awesome option for setting up a p365 build.
I was on the fence about buying the sig custom shop FCU or trying to find a deal on a used p365 to start my build. I wanted to save money where I could and luckily ran across the black PVD option on ABPrototype's website. This unit is much lower in price than the customer shop FCU, so when it came back in stock, I jumped right on it! The team over ABPrototype was all over my order and even answered the FFL email over the weekend! You couldn't ask for better service! The fcu arrived at my FFL in a couple of days, and I picked it up with no issue. It met all my expectations, and I felt like I got a deal after all was said and done. Thanks, AB Prototype Team!

Excellent communication and even personal emails regarding my local FFL’s license. They let me know when the information was acquired and when the item shipped. Fast shipping and the product was exactly as pictured and described. Product works perfectly. Will be a return customer.
