I like both. I've never owned a true Commander sized 1911, just 4" models. Which are basically the same thing IMO. I'm on the fence about going with a 5" or a 4.25" for my next 1911. Let's here some pros and cons and just pure heart felt opinions and facts. I will say that if I go with the 4.25", that I doubt I have it bobbed. Well, fire away guys.
