Sig has .38 super barrels for $29.00 and I ordered one for my RIA. I also ordered a magazine. I have been thinking about this since I got the 1911 9mm and want to give it a try. I have been reading about this round for over 40 years. I suppose I will have to order a new set of dies next. When I turned 70, I swore I wasn't going to flirt with any new calibers, but it seems to have happened.

What is the best diameter bullet to shoot or will any of the .355 to .358 stuff work? I do not know yet what the diameter of the new barrel will be.
