Buzz-Dave T speaks the truth.
I have gone through 2 LW Commanders. By "gone through" I mean that after about 5,000 rounds of full duty rds. a crack starts just forward of the slide stop pin hole .I did change recoil springs after every 2,000 rounds.
I've been asking all around and some quite authoritative people have told me both keep on shooting it till the crack affects function;or dump it now! 5,000 is really the magic number with the Colt LW Commander and I would like to hear from anyone who has experience of 10,000 or more with Kimber.
And before you ask, I'll say it now -I don't use Shok Buffs.(If you want to know why, I'll reply to that in another post.)
Dave T,could you give us more information on what was failing or cracking on your Commanders that made you decide to retire or sell them?
Shalom
