I shoot Rowland level loads out of a .45 ACP chambered Lone Wolf barrel in my Glock 21. I use a 24# recoil spring and a LW compensator.
You must use a fully supported chamber because if you don't you will start bulging the brass down the feed ramp at .45 Super levels (~28k psi).
With a well supported chamber extremely high pressure loads are possible but then slide speed/battering becomes the problem. With a 24# spring and comp I shoot 250gr XTP's at 1250fps or so and 185gr Barnes XPD at 1475fps as well as 275gr Hunters Supply lead WFN @1250. These loads handle in the gun fine, Winchester brass is thrown 5-8' and recoil is not too bad.
Basically I have a light, high capacity (13+1) all weather auto that shoots midlevel .44 mag or Ruger level .45 Colt loads.
