The original Jurras made Automags came mostly in 44AMP and 357Amp, not to be confused with 44 or 357 mag that revolvers shoot, if memory serves there was also a 41 AMP but I have never seen it. I have both the 357 and 44 Automag pistols, they are fairly reliable with factory ammo ( which is near impossible to get now) and not so reliable with made up ammo, feeding issues are common. To make ammo I have found 30-06 cases cut down and formed work better than 308 , I don't know why, but the 06s work better and last longer, it is time consuming to cut the cases down inside ream them then form them just to get raw brass. They are very fussy guns about the loads as well. $2000.00 US would be about what 1 in fair to good condition is worth, parts are nonexistant, so I shoot mine very seldom. I prefer my Eagle in 44, much better operating gun :mrgreen:
