The Magnum Research DE429SRMB is a semi-auto pistol chambered in .429 DE, built around a 6″ stainless steel barrel. It holds 7+1 rounds and uses a 1-in-19 twist rate. This is a big-bore handgun, and its size reflects that.
The frame is stainless steel and the slide finish is stainless steel as well, so the pistol has a uniform look from muzzle to grip. Overall length is 10.75″. Unloaded weight is 75.2 oz, which is a lot of handgun to carry and a lot of mass to hold steady at the bench.
Sights and controls
The sights are combat-type and fixed. There is nothing to adjust, so what you see is what you get. A manual safety is fitted, giving you a control to engage when the pistol is loaded and not in use.
This pistol suits shooters who want a large semi-auto in .429 DE and who care about a stainless build. It is a range and collection piece first, and a good fit for anyone who likes heavy, full-size handguns.
For gear, plan around the weight. A padded, lockable hard case makes transport easier. Add .429 DE ammunition, spare magazines, quality eye and ear protection, and a sturdy shooting bench or rest. A cleaning kit sized for the caliber helps keep the stainless barrel in good order.
