Pillager, MN – ( – Magnum Research, Inc, maker of the world renowned Desert Eagle pistol and leader in innovative firearms design and manufacturing, is proud to announce the launch of the new 429 DE pistol cartridge.

Magnum Research has developed a new, fast, powerful .44 caliber pistol cartridge. The 429 DE (Desert Eagle) was designed to enhance the famous and powerful Desert Eagle platform. This cartridge has a 25% velocity increase and 45% energy increase over a 44 Mag (240 — 6″ barrel). It has a velocity of 1600 FPS with 240 grain bullets and 1750 FPS with 210 grain bullets.

The 429 DE features 30 degree shoulder headspaces and a neck long enough to properly hold and crimp a 240 grain bullet without set back under recoil. Based on the famous 50 AE cartridge, the 429 DE is made with Starline brass, and loaded by HSM in Montana with Sierra bullets.

“This new cartridge was engineered and designed specifically for the Desert Eagle Pistol, keeping in mind that the DEP is known world wide for its awesome firepower and performance. The 429 DE propels that history into the future,” says Jim Tertin, Design and R&D for Magnum Research.

The 429 DE rounds are available in boxes of twenty and distributed by Magnum Research, Inc. Available options include: 240 grain soft point (DEP429DE240JSP) MSRP of $42, and 210 grain hollow point (DEP429DE210JHP) MSRP of $42.

To accompany the 429 DE cartridge, Magnum Research will soon be releasing a lineup of 429 DE 6-inch barrels in a variety of finishes. The 429 DE barrels will be compatible with any MK19 USA or Israel Desert Eagle Pistol with a wide .830” rail on top of the barrel and uses a 50AE magazine and bolt. More information on these barrels will be announced soon.

Note: The 429 DE is similar to, but NOT INTERCHANGABLE with, the obsolete 440 COR BON, but properly engineered with a sharp 30-degree shoulder, consistent headspace and reliable function and velocity.

Please, PLEASE do a 10 inch barrel. I’ve been wanting a 440 corbon in 10 inch for years, but they virtually unobtainium

Rick VanVoorhis

found out there has been talk withing Magnum Research about a 10 inch barrel. now that would really make the round sing.


Looks like a great idea long overdue. With all the other massive magmum cartridges out now, the .44 mag is quickly being relegated to short barrels and compact frames. Not much reason to tote around a 50 ounce .44 mag revolver when for another 6 ounces one can carry the .500 S&W! And for sure there’s little consumer interest in a 4.5 pound oversize “brick” just for relatively “weak” .44 magnum! That’s why the DE .50 AE took off like it did, but a bottleneck .44 looks to be the right next step. It will move the cartridge solidily up… Read more »

Has any of the 429 been sent to Australia ? if so who handles them ?


So, they invented… the .440 Corbon. The CorBon gets higher velocities to boot.


I think they need to change the name to “Desert Beagle”. Big, heavy, gas operated handguns are kind of dogs.


Not a new idea–and does it come with a wheeled carriage to carry the thing?

I read an article years back where the author referred to the Desert Eagle as the world’s first crew served handgun. Never forgot that line.

Charles Askins said that when the gun first came out.

Hey Kahr, how about a rifle for the 429DE? This would be a great hog gun, also good for deer and bear! How about necking it down to .41 caliber? (41-429de) and a rifle for that? Make a 10 round magazine available dont make it too expensive so most people can afford it.

Dr. Strangelove

Sounds great! I think that I’ll pick one up along with a couple hundred rounds and go plinking.


If you buy one you better buy a lot of ammo and or brass.
As I predict it well not me around long.
