Mags, I'm not doubting that your Swartz safety equipped Kimber is reliable. I'm just taking into context that the OP is looking for a duty gun. Personal experience, combined with comments like those from Mr. Yam & others who are very knowledgeable of 1911s, makes me strongly caution anyone who's looking at a FP block / safety equipped 1911 for duty use.
I've owned quite a few 1911s from various manufacturers in my relatively short time with the platform. Of the 1911s I currently own, three are Kimbers, and one is a Springfield. Two of the Kimbers are Pre-Series II guns, and the other is a Warrior. The Springfield is an old base model loaded with parkerizing, a pinned solid black front sight, and solid black Novak rear. All of the Kimbers (from the early Yonkers Classic Custom, to the later Stainless Target, to the recent Warrior) can interchange field stripped frames & slides; and the frame rail / slide rail tolerances are nearly identical. Kimber's tolerances remaining that tightly controlled over a pretty wide production period is very impressive to me. If I could only keep one 1911 it would be my Warrior. I'm not knocking Kimber, but I wish they'd offer their full line without Swartz safety, at least as an option.
