Who uses/has a compensator for their pistol?

[Guest LLArms]

Have wanted for a while to model compensator after the H&K USP Match pistol that has long since been discontinued.

Originally the design was going to be for a Glock 17, but that has been gone a while so I am having my machine shop partners make one for my CZ75 Duty pistol. I just want it for fun at the range and to help my wife, but I am curious if there are certain types of pistol matches  (open class?) that allow for these?

Does anyone use one of these on their night stand gun?

And now my master level artistic skills at work...  <dontknow> <laughs>

And for reference, the old H&K USP Match:

just got rid of a ported xd. it was pretty cool and had less snap then a non ported .40. nothing id go out of my way to have though.

I'm going to have my HK USP converted to .460 Rowland and that will require a ported barrel. I heard the porting is pretty effective.

Well she ain't perfect, but not bad for a 3D modeler noob...
