I was wondering about the design for the .445 compensator/muzzle brake. I love the design and it is very aesthetically pleasing to me. I was wondering if anyone knows the physics of how this actually works. I have guns with compensators but this design is a little different to me. Does anyone know what percertange of barrel jump and recoil it tames? Also when it first came out. Thanks, Gary.

I do know it is the "second" design or better it superceeded the "ported" design.
Basically this is an extended shroud with end cap. The barrel screws into frame as normal, then a barrel nut secures it (requires special barrel nut tool).. then a screw in cap closes off the shroud. As the bullets exits the barrel and jumps to the end cap, gases can escape through vents in the top of the extended shroud. No gases pass into the cavity behind the first barrel nut (which is a VERY good thing).
I have never owned one, and probably will never have the funds to do so, though I agree they are very cool, both in concept and function.

in that order.

Great description, Pine.
I'll toss in a pic & some additional thoughts. Gary, all the action happens in the spit second between when the bullet exits the barrel & when it exits the shroud nut. As the bullet enters the hole in the shroud nut, it sorta "plugs the hole" for a short time, redirecting the gasses behind the bullet upward through the comp slots. This results in a downward push on the end of the barrel & reduces barrel rise & felt recoil.
I thought I ran across an artist's rendering of the DW comp in action at some point, but I sure can't find it today.
I bet there's some literature from the period to show it's function, or maybe even a magazine article.
This compensator design was only used in the Palmer era, as far as I know. It's possible they were working on the design in the very late Monson years, but I have yet to see an example of one. Likewise, I don't recall seeing an example from the Norwich era.
As always, any opinions or evidence to the contrary are always welcome.

There we go! Ya see, as usual, I often forget half the facts I'm trying to spout off with.
Thanks Ron, I stand corrected.
Ok, so someone pop in here with a Monson comp shroud & I'll eat my shoe...with ketchup.

Based on the research I've done Wesson Firearms of Palmer, Mass filed a patent on November 19, 1992 which was approved on April 26, 1994. The Inventors were Robert Talbot, Seth K. Wesson, and Edward Arventos.

I appreciate that information gentlemen. I have that .445 with the compensator and I am amazed at it's design. Maybe EWK could come up with something similar for his heavy barrels. Just a thought!
