#AB PROTOTYPE MANUAL#

The grip I sent them is different than the one I tested the gun with as I'm still waiting on another vendor to finish my full sized slide milling for an optic.

The required milling on the grip module to accommodate the safety lever is also top notch. The fit and finish on the parts is excellent, and they perform flawlessly, as you would expect.

It was explained to me that they usually do the FCU frame milling in batches, usually every other week, so I must have hit it just right, nice! I am here to tell you guys, it's money well spent! Turn around time was about a week, from arrival at their location to return to me. For 199.00 I could ship directly to them (with required documentation as they are an FFL) they would do the conversion using only Sig parts, and include shipping back to me directly, so no PITA FFL or fees. I came across AB Prototype, San Diego, CA, in another thread here, and figured I would give them a try. 45 ACP, and I really don't need another one or want the hassle of dealing with an FFL, and my local pistol licensing bureau, which would add more cost to already expensive FCU. (I'm not here to argue the merits please, but I'm a 1911 guy at heart, so there you go) Even though later versions were offered with this as a factory option, those FCG's are still tough to find in.

I bought my P320 pretty early on and since then I've wanted a manual safety.
