designed pretty much the same cartridge thru the years. Not sure why it was dropped. If you like the Desert Eagle then the 429 DE is the way to go for big dangerous animals.
On the other hand if you want power in a 44 caliber handgun, our 429 GNR would be hard to beat. here are the comparisons from the ballistics I read in an article recently.
429 DE with a 200 grain bullet...1628
429 GNR with a 200 grain bullet...1973

429 DE with a 240 grain bullet...1533
429 GNR with a 240 grain bullet...1790
The 429 GNR data done by Sean Harper who is one of the most knowledgeable ballistic people I know.
That pretty much tells the story.
