P320 FCU
9 months ago This is the only place I could find these in stock and it arrived at my FFL very quickly. Like every other order I have placed here, I got notifications upon shipping and delivery which I thought was nice. The only thing I noticed, and this is focused at the manufacturer and not sigsauerparts.com, is that the trigger isn't as crisp and has a bit more slop than an FCU I handled in the past. I'm not sure if this is due to a redesign from the issues that the P320 has experienced but this trigger at least was not as smooth as I was hoping it would be. Even still, it makes a nice shooter and I would buy it again!

320 FCU is awesome
10 months ago Really was surprised at the FCU. I dropped it Into my handgrip, lubed the rails to my liking and put it together. I compared it side by side with another 320 that I installed an apex trigger in. The trigger in the Sig FCU was just as nice as the custom trigger in my other 320. I was very please. The Ti nitride finish is a pleasure to look at (Gucci as hell) and it functions nicely keeping all of the mating parts nice and lubed.

Sig Sauer P320 FCU
11 months ago Simple drop-in installation into appropriate Sig gripframe. Dry firing, trigger is a bit heavier than I anticipated, but it probably will lighten somewhat with use. I can see why these have been so hard to come by!

Great, but pricey
1 year ago This FCU is a great product. Trigger is light and crisp. Feels very similar to the FCU in my p320 Legion. However, the price is really high. It's a superior product, but for another $100 i could have had a complete brand new p320.

1 year ago I have been waiting for this product for over six months and it is well worth it. It is expertly crafted and is the building block for my custom pistol.
