The best and only P320 jig May 10, 2024 : HairTriggerFlicker from North Idaho   Arrived as described but now with improved Allen head screws, no more Phillips head. Much easier to get the jig nice and tight. Fit and finish is spot on. My first MUP-1 only took about 30 minutes of slow and steady work. Be sure to use a drill press with cutting oil and use a light pecking motion when drilling to keep the heat down. Was this review helpful to you?

Outstanding service May 3, 2024 : JJ from United States   MAS only carries quality items.  The big surprise was the phone call to explain a question I had sent an email about.  Usually it takes days to get response from any vendor.  Well, I recieved a call within an hour!  You just can’t find that kind of service anymore.  It made a loyal customer out of me for sure.

Great company, great product April 28, 2024 : Russ from WI United States   I got mine for cheaper than it's listed for right now.  I'm glad I bought it when I did as I didn't realize the price would go up $30. Msd ships fast, great communication and great product.  I'll definitely be a return customer. Was this review helpful to you?
