Holland Radial Muzzle Brake On XP-100 handgun

[Len Backus]

Here are 3 clips of Darrell's brake on Ernie's 7mm Dakota (magnum cartridge) XP-100 handgun. This is a stout load for a handgun, even if it weighs about 11 (?) pounds.

The first shot is with a normal grip on the gun by the shooter.

The second and third shots are is done with a light 2-finger hold by Ernie. Notice that there is no torque.

I have one of these on my latest rifle, also in 7mm Dakota. I can't say enough about its effectiveness.

Great job, Darrell! gun)

By the way, no prairie dogs were killed (that I know of) during the filming of this video.

 

[davewilson]

is this a "radial" muzzle brake or the "quick discharge" that's on his site?

 

[Len Backus]

The brake in the video is the radial.

Anybody have a good closeup picture of the Holland radial??? It's not even listed on his website.

These video clips are Darrell's new Radial Brake (not the Quick Discharge). I do not believe the new brake is on his web page yet.
here is both brakes:

The top one is the Radial.

Thanks for the picture Ernie.

Dick,
You are welcome.
Do you like my picture base for the brake?

 

[davewilson]

Ernie, it appears that the flanges between the ports are thinner and the ports a bit wider on the radial design. is this an optical illusion? also do they come already tapped in certain thread sizes?

Perhaps I am seeing things, but to my mind that looks a lot like Kirby's Pain Killer.

 

[Ernie]

There is some similarities, but Darrell revealed his brake two SHOT Shows ago.
Darrell's brake is also radiused, not just angled.
Hopefully, Darrell will come on and explain better than me.

i talked with Darrel today about this design. the ports are not machined, but cast into it. the baffles are sherical or concave shaped, not flat sided. the ports are also slightly larger than the quick discharge and the baffles a little thinner. the holes on top are machined. no, you can't get one without the holes on top. he talked of 2 sizes, don't know if there are others. one is a few thousands under 1" and the bigger is around 1.20" in diameter. thread size for the 1" is 9/16, the 1.20 had threads of 3/4 and another that's larger, forget the larger thread size. overall length is a little longer than the QD. price was $125

I would say this brake and Kirby's pain killer do pretty much the same thing. direct the gases back towards the shooter a little instead of straight out the sides giving a bit more recoil reduction. i assume they will be available in chrome moly as well as stainless steel, forgot to ask.
