Defiantly will have to put together another 40 single stack. I built one in 1989 before ramped barrels were available for the 40 and no powder companies had loading data. I had to develop my own loads.
After blowing out way to many cases in my face (and still have the scars to prove it) trying to make a major load I gave it up.
Matt, will Springfield sell this set-up to any FFL? Or do you have to be SPECIAL……
