How well does the Coonan feed the various SJHP and lead hollow point .38/.357 magnums? Can it only run FMJ loads?
While I haven't tried any, JHP should work, if not, it would be an individual gun issue, not a design issue.
The Coonan is recoil operated. Not gas operated like the Desert Eagle. The Coonan can shoot any FMJ, JSP, JHP, or cast bullet without issue (other than an individual gun might not like a given load).
With the Desert Eagle you must stick to jacketed bullets (with the jacket covering the base of the bullet), or you risk clogging the gas system. Desert Eagles are ok with exposed lead bullet noses (JSP, JHP), but need full jacket coverage over the rest of the bullet, or you will have issues, at some point. AND, a clogged gas system is NOT covered under their warranty.
The Coonan is like the 1911 it resembles in its ability to eat ammo. Meaning jacketed or lead (the lead must be hard enough for a semi auto, like any semi auto), the gun doesn't care much. Different load levels can be made functional by changing the recoil spring. The Coonan will shoot (and feed) .38 Specials with the correct spring for them, and I understand that the new Coonans come with the needed parts for conversion.
The Coonan is much more versatile then the Desert Eagle, in terms of the ammo you can use. Bigger and heavier than a 1911 Govt model, its still smaller and lighter than the Desert Eagle, and because of that, more people can more easily use it. It is thinner than a magnum revolver (no cylinder), and while larger than the usual duty class autos, its not much larger, still within the range of practical carry, I think, if only barely.
Another thing I like about Coonan is the attitude. Honest might be a good way to describe it. In a fairly recent Coonan ad I saw they make a point of stating (in a noticeable fashion) something like this...
"If you're looking for your first handgun, this ain't it!!!"
gotta admire that.
Its not for the tyro, its not for everyone. But if it's for you, I don't think you will be unhappy.
