Description
Customer Reviews
The new 80% Sig Fire Control Unit (Modular Universal Pistol or MUP), is compatible with current P320 upgraded parts, including SIG’s line of “drop safe” firearms. You can use this insert to make a 9mm, 40 S&W, 357 SIG, and 45acp (with slight modifications). That means this SIG P320 insert is extremely versatile. Design a SIG P250, a P320, or even put it in the EXO-1 Chassis system.
This quality insert is made from type 316 stainless steel, so it will last you through years of use.
With this insert, you have a base from which to build your new favorite firearm.
To finish the insert, you need to complete the following:
Drill All Holes
Bend Slide Rails
Trim Rails to Size
Complete all of the operations on your MUP insert with a drill press jig (sold separately).

MUP review
The MUP is is well made but easily bends out of shape if you try hammering your pins in when you install your parts. Make sure the sizes of the bits. The bits which came with my jig bought here were all but one too small for the pins that came with a quality lower parts kit bought elsewhere. You must do a lot of filing to take the sharp edges off so the upper will slide easily. Do that and make sure the holes for the pins are the proper size and the lower will be exactly what you need for a proper firearm.

this does the job
With some TLC the MUP can be turned into a P320 FCU that works just as well as a factory part. I will say I have a mill and press. I'm not sure how someone with a Black and Decker home user drill and a file would fare. The safety slot could be a real challenge. I took my time, especially with the rails, and the fit was perfect. Worth the time and $ invested.
