Thanks Oneida Steve. A little "hands on" info was what I was looking for. There is not a whole lot of information available about this cartridge. What is available seems to be old reports that came out right after the cartridge came on the scene, before the .40 S&W/10mm Auto became popular, and later info after the success of the .40/10mm, and demise of the .41 AE. The reports on the cartridge from the 2 different time periods seem to net totaly different views of it. In the beginning it was touted as a very powerful cartridge, close to the Rem. .41 Mag., but the 10mm seems to have out performed it. It's hard to get a good picture of what the round really is, but I think I tend to go with the later reports of it being slightly more powerful than the .40 S&W, and slightly less than the 10mm. 10mm is about the upper limit I want as far as power goes in a 1911, and I was worried that the .41 AE would be too much for reliability in the gun. Brass is available, but pricey @ about $1.10 a pop for this round. I want to be sure that I can shoot the thing without hammering a frame or slide before I invest any more into this project. Thanks again!
