If you're doing a Sig Sauer® P320™ compatible build, you'll need a lower parts kit to get your MUP-1 up and running. That's the part legally considered the firearm and also the part you keep when you're changing out frames, slides, etc., to convert your sidearm into different P320™ pistols. Well, this is your lower parts kit. It comes with all the parts you need to make your 9mm, .40, or .357 chambered MUP-1 fully functional. See below for more info.
