I would use the Desert Eagle on the range and store it in a Gun Vault in my bedroom. Presently, I use the same Colt Defender as my CCW and home-defense weapon. The Desert Eagle, being gas operated, is an extremely finicky handgun. The slow burning Ball powders that the cartridge requires necessitate frequent cleanings to remove the unburnt powder residue as often as every 50 rounds. Failure to adhere to a rigorous cleaning schedule will render the piece useless.
Cast bullets are out of the question.
The removal of this clogging is a job for a gunsmith. A bronze phosphor bore brush will not do the job. The pistol, itself, has all the ergonomics of a cinder block. It is heavy, and not at all suitable to concealed carry. The Desert Eagle has never appealed to me.
