Late in this discussion I know.
I shot several buddies FA's over the years, but never shucked out the coin for one. I spent a lot on other wheel guns trying to get them to shoot as well as FA. It can be done but why.
It now have five and am pretty happy camper!
As mentioned above, cry once.
Do as I say not as I did, don't wait long in life to own an FA.
25+ years of playing with all sorts of handguns, I have run across exactly one individual that had any bad to say about them that went unresolved by FA, and I question that.
The 45 Colt cylinder is a good move on your part. The 454 is good, but I find it a bit obnoxious. I can load 45 Colt up to levels I find tough ;-).
