There are still companies making the .44 auto mag. It was not excepted when it first came out but there is still some intrest in them. check out
www.wildey.com they are making some very interesting auto's. I have often wondered why the 10mm never caught on like the .40 did it is almost the same round. 10mm = .40in. ? I have heard some say I love my .40 it shoots great , I traded my 10mm in on it ?????? Okay!!!!And its alot more powerful---What!!!! Good luck finding one let us know if you do.
