To answer your question, the Pro Carry Ten II is a very reliable hand gun. It is light weight compaired to any 45 that Springfeild or Para puts out (in a 1911). I own one in each size. Ultra, Pro and Custom. Any of which would make a fine carry gun. The Kimber KDP only comes in 40 S&W, right now with a 9MM , coming soon. Although Kimber has some high end guns. The Ten ll 's are not one of them. The .45ACP round is the best round, bar none, to put an attacker down with one shot to the body. (Not everyone has Seal training two in the chest -one in the head) Yes, the Navy went to the Sig Saur P220. And Sig Saur makes a fine double-action gun.But the Marines went with the Kimber Warrior .45ACP 1911. The Kimber was put up against Springfeild, Colt, Para -Ordance,Smith&Wesson and Yes, even Sig Saur made a 1911 to put in test's. They were all tested under the same harsh conditions and the Kimber came out on top. So it really boils down to which type of action you want. If you can, see if you can find anyone that will let you shoot either and/or both guns. By the way I do own a Sig Saur P220. It's a nice hand gun. It cost about the same as the Pro Carry Ten II, but I still carry the Kimber. I am a Marine, 1911 pistolsmith and a factory certified Glock armorer. So good luck with what ever your choice is .
