JD,

You'll get some expert advice here shortly. I have no experience with the Colt, but own a S&W model 1917. I do know that Colt did not recess the chambers in the cylinders and so you cannot load .45 ACP in them without half or full moon clips. I don't think that's such a big issue; full moon clips are easy to find, and in most cases even the half moon, it's just a bonus that you can load them without. Extraction can be a problem though, mine just drop out, but some say they must use something (like a pencil) to poke them out. In general, most feel the S&W is of better quality for both fit and finish, and I know of at least one period US Cavalry general officer that preferred the S&W over the Colt, but if it's a good buy, I'd go ahead and get it; I understand they are good shooters. I prefer the S&Ws any day, but if I came on a good deal for the Colt, I'd snap it up in a minute as I'm pretty fond of .45 ACP revolvers. You can always get a S&W later!
