I just purchased the Tisas .45. I have a number of other Colts plus Springfields and original U.S. property marked 1911 and 1911A1s. Good looking .45 from the outside as I haven’t taken it apart for cleaning and lube plus breaking it in. One thing.... it has the strongest recoil spring I have ever encountered. Does anyone suggest changing the springs out for comp springs or anything like that. They also have a 9mm in the 1911 style. What do you think of the 9mm?
