Its not a colt. But I'm excited for my first big bore too. Just bought a s&w hand ejector in .455. Pretty excited. My victory in 38sw is a tack driver, I love it .
Sorry to dirty up your colt thread
I had a 455 Webly in a S & W and a Colt New Service in 455 Eley. The Smith is the nicer handling IMO.
Post it up when you get it
