There will be a certain amount but how much? I don't know what the specs for a colt are. I have experience with S&W. Some one else may chime in with a good resource but all you need are a good set of feeler gauges. I think a thou would be it at most. Ideally of course you don't want any. Did your dad own it since new? Did he put alot of rounds through it? Were there any hot ones or did he just shoot mild ones?
