I picked this up this Freedom Arms Model 83 Field Grade in .454 Casull locally yesterday used for a great price. Freedom Arms sure makes a very high quality, and heavy revolver. The only thing I don't like are the rubber grips. Has anyone ever sent in thier Field Grade to Freedom Arms to have Premier Grade grips installed? How long did it take? Can you shoot .45 Long Colt in these revolvers? I'd like to spend some quilty time at the range w/ it without beaking the bank, or my wrist. The mfg says to only shoot .454 Casull throught the revolver because of the tight chambers. It seems to me that if you clean the cylinder chambers well after shooting the shoorter .45 LC rounds and remove the carbon build up that there should not be a problem. The gun is really built like a tank & is a pretty cool piece if kit.
