Is this fcu the customs works?

Hi Harry and welcome. Yes Sir it is. This P365 FCU Gold from Sig Sauer's Custom Works brings a distinctive appearance to your custom firearm. Its titanium frame ensures a strong foundation, fitting perfectly with Sig P365 parts. The flat face trigger, combined with the golden nitride coating, adds both performance and style to your build. As with the standard FCU, it ensures consistent trigger pull and responsive action. Cheers and stay safe!

Hi William and welcome. Yes, it is compatible with Sig P365 parts and designed for both 9mm Luger and .380 ACP. Cheers and stay safe!
