I posted this on 1911 forum also. As you can see from my involvement in another thread I am getting rid of my XDS .45 due to its unreliability. So I am looking at either a 3.3 inch Sig Ultra 1911 in . 45 as I have read nothing but stellar results and apparently Sig has solved the reliability issue with a sub 4 inch 1911. However that it is still something weighing on my mind. I am also looking at a Sig 938 9mm. My local gun store has both models that I want but can only buy one, thus these two options. The pistol would be used as a back up gun and summer carry. I already own two Springer 1911's a full length railed dust cover ( FBI contract ) and what I carry for off duty now a Champion Operator. So I am familiar with the 1911 platform. One of the qualifications that I must pass is a one handed hip shoot at a close distance so the pistol must be able to be shot with one hand and function. The rounds we use are the Speer Gold Dot 230 grain in .45 and 124 in the 9mm. Luckily one of my co-workers has a 3" Kimber hes going to let me shoot and my other has a Sig 938 and is also allowing me to shoot his so I can compare. So any of you that own 3 inch or have in depth knowledge of the 3 inch 1911's please chime in also those who own a 938. Even though I know shot placement is key, I am just used to a 45 as I carry a Glock 21 for duty and the 1911 for off duty. I have shot the smaller Glocks and I don't like them, if I had my choice I'd carry a 1911 for duty. A small bullet can get bigger when it expands but a big bullet always stays big. I think I can sacrifice stopping power for reliability I refuse to go to a .380 and am not a revolver kinda guy. Thanks to all who reply and have a great weekend.
