Any comments regarding the types of ammo that seem to shoot better out of the Ultra CDP? I am asking because there have been some comments made about the fixed sights on a Kimber and the only way to adjust is to either file down the sight or use heaver or lighter ammo. depending if you are shooting high or low.

All my Kimbers wear fixed sights and all shoot right on point of aim with all loads tried. For practice I would use any decent quality inexpensive FMJ 230 gr. such as UMC (Remington), USA (Winchester), or American Eagle (Federal). For practical defensive work I would use either the Speer Gold Dot or the Federal Hydra Shock JHP. Now I would use the heaviest load that would reliably expand out of your short barrel. Start with 230 gr. and work down through 200, 185, 165, etc. Don't go any lighter than you have to. You can test expansion in milk jugs or 2 liter bottles filled with water and lined up. You can also test penetration. It usually takes me about 4-5 jugs to catch a good expanding hollow point.

mlbdg - if you are talking about the Ultra CDP, then you have 3 dot night sights, correct? If so, filing will not alter the location of the dots, and assuming you are aligning the dots to aim would not affect where the gun shoots. If you are aligning the top of the front sight with the top of the rear, then filing the top down would raise point of impact.
