Most Helpful Positive Review Need some further develement.
Make sure the threads on your barrel [installed in the slide] go all the way down the barrel to the very front of the slide or this thing cannot be installed properly. My threaded barrel is at a gunsmiths being threaded further. My 9mm Shield will look fantastic with this thing installed. Tooooooooo bad they do not make one for the Shield in 40 S&W..

Samson comp

Like how comp doesn't tighten on barrel but tightens on barrel sleeve.

Very disappointed

by Michigan Mark, Verified Owner from MI, United States Written on December 26, 2024
This is a great looking compensator for a Shield/Shield Plus, and the mounting setup is also praiseworthy. I really wanted to like this. But the one I received was defective as the inside threads on the "thread protector" portion were poorly machined and it would not go on my SilencerCo Shield barrel. My barrel is not the problem, the threads on the Sampson comp were visibly defective. It looks like other people received good ones, and I just got a bad apple. But I'll move on and try a different brand - basic quality control fails on something is straightforward are a no-go for me.
Pros:
  • Looks nice
  • good size
Cons:
  • Quality Control
  • poor machining
Would recommend: No

Amazing compensator

by Theraos, from KS, United States Written on March 9, 2024
This comp works flawlessly and very noticeably reduces felt recoil. People say they can't notice much of a difference if at all but it was blatantly obvious to both my girlfriend and I. The manufacturer recommends 124 gr or heavier bullets to cycle, however I have put a couple hundred rounds of cheap bass pro 115 grain training ammo and had zero issues. The ability to quickly remove and attach the compensator is very handy as well.
Pros:
  • None
Cons:
  • I can only find 3.6 inch barrels or longer which leaves a gap between the slide and comp
Would recommend: Yes

M&P Compensator

by JawKnee, from FL, United States Written on April 28, 2023
I bought this for my M&P 2.0 9mm Compact Bull Shark Gray pistol. It looks great and matches the slide perfectly. It was relatively easy to mount in line up. I can't wait to take it out and see how it performs.
Pros:
  • Looks amazing
Cons:
  • none yet

Pocket compensator

by Muzzle, from UT, United States Written on July 13, 2022
10/10 highly recommended for any firearm carrier out there, The pocket compensator is very reliable and also portable it does not have any cons in my opinion. My Smith & Wesson suits better with the muzzle break from Opticsplanet.com for anyone that is questioning if it is worth it or not it is 100% worth it

samson comp

by samson comp, from TX, United States Written on February 28, 2022
great all around! would recommend to my friends and family, makes my shield shoot flat and will also fit the older and newer generations (ie) the shield 2.0 and the plus. best to take it to a gun smith as it can be difficult not to strip the nut within the comp
Would recommend: Yes

Great looking compensator

by Kmendez, from FL, United States Written on April 7, 2021
It looks really good. Material and design are very good. Looks very quality. It fits perfect. And once secured and lock tight it stays in place. The MP 9 shield shoots better now, less snappy and seems to follow back in target faster and easier. Overall satisfied with this purchase
Pros:
  • Fits perfect mp9 shield
Cons:
  • A better system to attach without having to use lock tie
  • a faster attachment mounting system needed
Would recommend: Yes

  • None
