My advise is buy it, you’ll love it. I had constant stove pipes the first 200 rounds of 230 fmj, called Kimber, they wanted it back. Only took 2 weeks to get it back and now 250 rounds later it runs flawlessly. It’s now my EDC. If it doesn’t work right Kimber will make it right CS is great IMHO. Follow Kimbers suggestions and clean it first using 230 grain FMJ for the first 500 rounds.
