I'm going to go out on a limb here and guess most of your handgun shooting experience is with adjustable sights. Very generally speaking, if one is right handed, shots hitting to the left are typical if one is not using good trigger technique. Make sure you are pulling the trigger with the pad of your trigger finger, pretty much under the nail. Do not place the trigger in the crease of the first joint. Even though that may feel more natural, pulling the trigger with the finger placed in the crease will tend to push shots to the left for a righty. Our fingers are really not able to pull straight back. The only thing we can do is curl our finger to pull the trigger. If the trigger is resting in the crease under the joint of the trigger finger, that will tend to push the muzzle slightly to the left when firing. Pulling the trigger with the pad of the finger allows us to pull the trigger a little bit straighter than in the crease.
I can tell you whenever I buy a used revolver with adjustable sights, the rear sight is almost always cranked over a little bit to the right, to make up for poor trigger technique.
That Colt should be able to put your bullets exactly where you want, if you do your part.
Hi
Thanks for the theory. However I have plenty fixed sights handguns that I shoot straight so ...
