Hello all. New to the forums. For John, what is your take on the 1911? What do you feel are its pros and cons and your experiences using it as a lefty, etc.? Additionally, what is your opinion of .45 ACP, .40 S&W, .357 Sig, vs. 9 mm, i.e., the long version of why you are a 9 mm guy? Apologize if you have addressed this elsewhere. Thank you.
