    This is my first comp and boy let me say this thing is beast!!! I did plenty of research and hands down you just cannot beat the quality and functionality from pmm.. iv tried other comps on friends firearms but none worked out the gate without swapping springs and other shenanigans. This thing rips out the gate, i have 500pluse rounds and no issues. thanks guys for a beast of a comp and barrel..

    This is a really great product. I’m very impressed with the effectiveness of this comp even with standard 115 grain ball. It just gets better with hotter defensive loads. Admittedly, I could have clocked the pretension a little better the first time I installed it and it worked itself slightly loose, but not a real issue. I bought another shim set and was very meticulous about following the online instructions, and several hundred rounds later it’s holding up like a champ. If you’re on the fence I would not hesitate to purchase this.

    Great place to deal with. love my new barrel and compensator. this group is AAAAA. will do business with again anytime thank you very much

    Love the comp i’ve been shooting it with 115 but I’m looking forward to using 124 and 147 grain The way it’s mounted works great the fit also is nice and tight the only thing negative that I would have to come up with is the comp and barrel finish should be the same also a suggestion for future comp would be for STI 2011 the 4 inch model

    Purchased for my 19x and the product works perfect. Will purchase for my VP9 in the future.
