    That's not a comp...its a weight.

    I realize it's a 'match weight' . It also has benefits of being a 'compensator'. Wasn't in the mood to play semantics before my coffee, but..

    I would only put one on a full size P30 or USP but wondered if they really made much of a difference, and of course they worked wonders for john wick lol....
    I see a lot of glocks with comps on them but I think the glock fans just like blinging out their ugly from factory pistols!!
    Thanks for the info guys!

    No, it’s not “just blinding up pistols”.

    It’s difficult to describe how much muzzle reduction a compensator can do just by how we feel. Luckily somebody already did some objective measurements with, what I think, trustworthy results using Glock and some popular comps.

    https://www.omahaoutdoors.com/blog/2...nsator-review/

    The best measured in the above report was over 40% muzzle rise reduction. But I am very very sure it can be achieved much much higher, just watch those USPSA OPEN competition guns.

    It can be an effective compensator by redirecting the gas upwards when used with a standard length barrel.

    Another HK factory comp does pretty much the same with a standard barrel.

    I run a steel Match Weight on a USP 9 Expert. I can tell a difference when I shoot it. I like it.

    Exactly. An Expert barrel is 5.19” and a Match barrel is 6.02”. That difference in length, with a Match Weight mounted, forced a lot of gas from the muzzle to go upward which pushes down the muzzle just what a comp is for.



    Pictured is not an Expert but just for illustration.

    I’m interested in this as well. I’ll add the thread below, but basically lifesizepotato is saying that damage could occur to the frame via torquing action of upward gas, should one use the match style weight without a barrel of length which is adjacent to the leading edge of said weight. I think the ideal setup with a non-merkle weight would be to run a ported expert barrel from Jarvis.

    Can anyone confirm or deny long term frame damage with a barrel of inadequate length?

    I can only imagine that it may damage the polymer rail if the comp clams to only a small potion of the rail. If it clams to the full rail, which they all do, I doubt it would damage the frame as the polymer frame is designed to flex to absorb shocks. The force from the slide slamming back has much bigger impact to the frame. Plus, however strong you lock your wrist, your whole arm will offer crushing to the downward force from the muzzle to reduce impact to the frame. I wouldn’t worry about it on mine.
