Sig Sauer Custom Works P320 Fire Control Unit (FCU)

The Sig Sauer Custom Works P320 Fire Control Unit (FCU), is a serialized firearm and is required to ship to an FFL dealer. Starting with the FCU you can add P320 grip modules, barrels, and slides to make a customized P320 pistol. Want multiple custom P320 pistols? Just take the FCU out of one setup and place it in another. Everything from a sub compact concealed carry pistol to a competition X-5 is possible with FCU.

From the beginning, the P320 was built to be a pistol that could adapt to meet the user’s specific needs. From grip modules and magazines to custom slides, barrels, and optics, the P320 can be configured in thousands of different ways to make your P320 unique and exactly the pistol you are looking for.

    I was glad to get the back in stock email, however the FCU is missing the take down pin.

    • Dkfirearms (store manager)

      Bradley, sorry for the issue. The FCU’s arrive to us sealed in their packaging from SIG. Please reach out to SIG directly and let them know there was an issue with your FCU as we do not have any parts for the FCU and this will be the quickest way to get the issue resolved. Please keep us in the loop, with regards to the missing take down pin. SIG has great customer service and the issue should be resolved quickly, but on the rare chance that it is not resolved in a timely fashion, reach out to us via email and we will contact SIG on your behalf.

    DK firearms is legit. My order was shipped about 90 minutes after it was placed. My order was processed and shipped so fast I thought I was getting scammed for a minute. I ordered my FCU on a Wednesday, and picked it up Friday. Also, they provided free shipping which they didn’t have to. So I will for sure buy from these guys again. Also, my FCU is as advertised. Great product for builders like me.

    Excellent FCU at a fair price. Item received at my FFL in less than a week. My only gripe in the whole process would be that it would have been nice to receive an email confirmation that the item had been shipped to my FFL.
