A series 70 LW Combat Commander was my first pistol. I bought it in 1974 to carry when I was transferred to a store in the ghetto. I loved it and shot it a lot. Two bad things happened (one was self-induced).
1. I had it modified including a trigger job. The gunsmith misunderstood me and reduced it to a 3lb trigger pull. In my opinion, I couldn't carry it as a self-defence gun any more. But still shot it a lot.
2. It developed a crack in the frame.
Dang, I shoot it seldom, still like it, it is great to carry...but I don't. My father bought a Kimber Commander style which I will get some day.
In my older age (59), I carry various guns (practice with them all) and find that an inside the waistband holster transfers the weight fairly well for steel guns. I mostly carry a Kimber Fullsize Custom Classic, Glock 23C, or a S&W 325pd depending on where I am going. I can carry each of them in an IWB holster...though the 325pd weights 28 oz loaded...carries high. All of them can go under a polo shirt.
