normally, my colt has always shot exceptionally well.the other day however i took it to an indoor range once again to shoot along with a new ruger 9mm i just got.fired the p-89. accuracy and functioning were very good,it fed every type ammo and accurate. next i shot the colt to practice.25 yards.shots were hitting about 6" low from point of aim.adjusted aim and next bunch didnt even hit the target but overshot it.none of the shots grouped at all but were scattered like fliers.switched to different ammo and got the same results with them all.what gives?the last time i fired it i was getting 2-3" groups and dead center.nothing seemed different in the cleaning afterwards,slightly more play in the slide but i wouldnt think that would cause that drastic a accuracy problem.there were no malfunctions,gun cycled perfectly but just couldnt group...ideas?

Could be the gun, but if you did a fair amount of firing with the Ruger, it could be that you were just tired from the recoil and the weight of the Ruger. Also, the guns feel different and the changeover can affect your shooting. Try again with the .45 when you are fresh and see what happens.

When they scatter like you say it's usually operator error, as Jim noted above. The 45 Colt Auto is easy to screw up with. I'm an expert. :(

There are military targets that show the various errors a shooter makes. But first you have to be able to get a group. Once you have the gun grouping, if it is low and to the left, for example, the target will tell you what error the shooter is making. There are quite a few not so obvious shooter errors that will make a super accurate .45 pattern like a shotgun.

It may help to get a coach. I had a couple military pistol team instructors who would watch me and give me pointers. It helps immeasurably to have somebody knowledgeable who can articulate exactly what you are doing wrong. HTH:)

I've noticed that after several hundred rounds, my accuracy and consistency starts to go to hell. At that point, I just pack up and go home, you're just wasting ammo and making noise when that happens. :)

I still haven't mastered My Colt 1991A1 like I have with My Beretta 92FS. When I only owned the Colt 1991A1 I shot it more accurately than any other gun i picked up. Now that I own a few different kinds of Handguns I haven't been able to shoot the Colt as well as I use to. I know its me and not the gun. I hate having to compensate for the bullet drop at 25yds though. My sites stink:barf:

exactly as i was thinking.when my colt was the only centerfire autoloader i had, it was accurate(rather..i was accurate)i carried it when hunting woodchucks along with my varmit rifle for close range dispatch.i think perhaps it was switching back and forth between calibers and just plain gettin tired did the trick.thanks.

I try to pretend that the reason I can't shoot well is that I own and shoot too many guns. (As good an excuse as any, right?)

In fact, it one wants to shoot well, it is good advice to stick to one gun or to very similar guns. That is the reason for .38 Special pistols on the 1911 frame, and .22 pistols that also have the feel of the 1911. The target shooter can fire .22, CF, and .45 or service pistol with the "same" gun.

I think you just talked me into buying an Ace or a .22 conversion kit. Shame on you:D

I might have missed it, but the lighting can have an effect on your shooting too.

For instance. First day of shooting, you are outside, it's really bright shiny out, and there are no clouds to throw shadows around.

Next shooting day, it's completely overcast, and noticably darker than the previous shooting day.

This is going to have an effect on your point of aim, how high or low you hold on the bullseye, and on other factors that can effect your point of impact.

You can simulate this change just by shooting outside one day, and then going to an indoor range the next. The lighting will be completely different.

I think it was Jim that mentioned something about dissimilar pistols. He's right about that. Just changing the grip angle of one pistol can really screw with the way you naturally point the weapon. This IS the reason for the Colt Aces' and the Colt Midrange (38 Spl) pistols. That way, three gun shooters never had to worry about changing their shooting position as they went from one caliber to another...

Man, wouldn't I just love to get a hold of one of those Colt Midrange guns, or maybe even a Model 52 S&W!!!

If you're tired of that 1991, then I can give it a good home!
