Aren't they chambered for 44mag/44sp and 45LC/45 Casull? Didn't realize they were 45ACP, too.
I've got one in 45ACP/LC. I really like it. Fun to shoot and has been very accurate. If you ever get out Lenoir/Boone way, give me a shout and I'll let you shoot it.
I had a 44mag and loved it but, I have medium ish hands and under heavy recoil it ate my fingers up. I could never quite get the perfect grip to tame warm to hot 44 mag ammo.
If you have bigger hands I'd go for it. The triggers leave a little to be desired but, a lil elbow grease and it was very pleasant.
