I've got one that'll shoot 4" groups at 7 yards all day long. Check bushing to frame fit.

Colt 1991 Commander accuracy
I recently purchased a Colt 1991A1 Combat Commander. I replaced the plastic trigger with a original colt s/s trigger and a metal mainspring housing and replaced the firing pin and recoil spring. That brought my groups tighter, but I noticed my shots are stringing up and down, not left and right. I read a thread in one of the posts a few days ago about someone else having this problem, but now I cannot find that post.
Can anyone help me with this problem? What do I need to do to fix this problem?
Is it a tuning, or a part replacement problem?
I am shooting 230 FMJ rem UMC, if that helps.
Any help would be appreciated!

...and I've got one that will shoot 1 1/2" at 25 yds. all day long.
As ElrodCod mentioned, the bushing fit is where most accuracy is gained (or lost). You may also check that you are maintaining consistent grip force, and consistent trigger squeeze shot after shot. Up and down groups are usually shooter induced.

What kind of groups and what yardage?
Sounds more like grip to me.........

I am shooting at 10 yrds, and the groups are stringing from 6-10 inches vertically and are only a couple of inches wide. I checked the bushing to frame fit and it is tight. The bushing to barrel fit is very loose compared to my full size 1911. I shoot 3" groups with my full size all day long with no stringing.
Thanks for the info. I'll have the bushing replaced and fitted to see if that cures the problem.
Thanks guys!

I've got two Colt 1991's, a fullsize Govt., and an officers size compact, both shoot basicaly the same group size at 12.5 yds, at 25 yds the fullsize outshoots the compact.
You'd have to shoot the gun from a ransom to tell for sure if its you or the gun making vertical patterns.
I've built and tuned a number of 1911s over the years and can't figure out why you think your upgrades to the gun would have any major affect on your group size. REAL accuracy has to do with barrel lockup in the slide, not the type of material your mainspring housing and trigger are made of.
Most people replace the barrel bushings in these guns, mine however needed different length barrel links in order to "tighten" them up on the lower lugs.

You didn't say if you bought it new or used. If used, besides the bushing I would also replace the springs. A weak recoil spring could be letting the barrel/slide unlock too quickly, causing the vertical stringing.
The bushing is the quickest and cheapest first step. If after the bushing, AND after either shooting in a rest or having a couple of known good shooters shoot of a bench, WITH good quality ammo, then start looking at the link, lockup etc.
Remember, try to eliminate the stuff like ammo, shooter error, etc BEFORE spending a lot of money having the barrel refitted.

Do you guys realize you're answering a question over 7 years old?

THen he'll be needing an answer ASAP!
New fitted Bushing!

What a hooot. Send it in for warranty work. :biglaugh:
Seven years...I knew dial up was slow but that's absurd.
Most new colt barrels seem to lock up pretty tight with the exception of the bushing up front. I usually install a N.M. bushing to tighten the groups a bit.
I don't care who ya are that's funny!:biglaugh::biglaugh::biglaugh:THen he'll be needing an answer ASAP!
