Hello! I am getting ready to purchase my first Colt 1911. My question is the choice between the Lightweight Commander O4860XSE and the Combat Commander O4012XSE. I currently conceal carry a Taruas PT1911 (to be replace with one of the above) with a N82 holster which does a great job of distributing the weight. My question: Is the 6.5 oz. weight savings going to sacrifice the durability of a Stainless Steel frame? I assume Coltalloy is of the 7000 series, which hardened to the highest strengths of any aluminum alloy. So my question is base on shooting 100-120 rounds per week through the Lightweight do I have any thing fear (except itself). It’s just that the Internet gives so much data (opinions) and wear seems to be a concern, real or not. Nothing erases doubt like wise words from people who use one or both of the above mentioned. Thanks and glad to be here!
