I'm giving it serous consideration. I have a couple thousand pieces of .40 brass picked up here and there. I don't currently have a .40, and (putting on my flame proof suit) don't think there is much a .40 can do that I can't do with the 9mm, 357 or .45 I already own. But, I have considered getting a Glock .40 and a conversion barrel to 9mm for it, just to widen my options in case ammo becomes hard to obtain due to increased regulations or a SHTF situation.
I reload all the calibers I currently shoot, and have also considered finding someone who wants to trade .40 cases for something I can use. Looking for .223, .308, .45, 9mm, 357, anybody interested?
