The Colt 1991 Series is a direct descendant of the original Colt M1911. A long trigger, flat mainspring housing and original style recoil spring system remain from the original M1911 design. Upgrades from the original include white dot sights and a lowered ejection port for extra reliability. It still remains “the standard” that everyone tries to imitate, but no one duplicates.

This the first time buying a gun online and did not know if i should. But could not find the gun i wanted local so i ordered it from buds and it was worth the wait. Got inin the time they said it would be here. Gun works awesome well of course its a colt. Right out of the box went through 100 rounds no problems. Hope this the first of many from buds. Thanks again buds.

Always wanted a 1911 since I was little, finally got it. Ordered this gun on a Friday and it arrived the following Monday, super fast shipping and nice pricing. Only 700 rounds through it so far, and the only problems I've been having are failure to feed on the last round with the Colt magazines on a few occasions: the slide locked back and the ammo is just rolling around freely and not seated in the magazine nor chambered for some reason. The problem is gone once I started using CMC magazines. A very balanced handgun.

When Colt's financial situation came to light, I decided I would like to buy three different Colt pistols and make one for use and two to put away after running a mag or two through them. My first one was the Colt Defender .45. Very happy with this gun and decided to make that my working gun. #2 was this Colt O1091. Beautiful gun and fine on mechanical check at pick up with my FFL. Took it home and disassembled for look over and clean, lube, etc.
I was shocked to find a lot of severe scratching on the weapon and in places I would not expect, such as two small and severely gouged spots under the slide stop. Slide was scratched on the inside and also the barrel was scratched in odd ways.

I have taken the gun to the range and shot through a couple of magazines and the Colt performed very well as far as function and accuracy. I do have to say that I very disappointed in the marks, none of which I was able to see until I disassembled the gun. I do not think I will be buying the third Colt. Too bad, as I really like them.

Finally, Bud's service was great and everything proceeded as planned.

Next will be a Springfield 1911, maybe the CZ 97B (when they get it again) or a big Brute like the 5-1/2 Ruger .44Mag Redhawk. All beautiful and fun, too.

Fantastic pistol! I would highly recommend to anyone looking for a 1911 with the fit and finish of a Colt. Bud's is far and away my best online firearm purchase to date. Everything went quick and easy at my FFL and they were happy to process another Bud's purchase. The gun arrived in perfect condition and shipping was FAST!! I have 550+ rounds through this pistol in two range trips and accuracy is dead on. Miss feeding happened at 200+ rounds with questionable ammo when the pistol was dirtier than dirty. When using federal, the gun kept going and going with no issues even at 300 rounds. I purchased another 8 magazines because this gun is so fun to shot. Already on to my next purchase from Bud's, I'm so pleased.

Ive had this pistol for about 1 year and have shot around 400 rounds with a couple jams using the cheap stuff. With ammo such as Critical Defense, no misfires.
Fit and finish, superb
Balance and sights, superb.
Accuracy at 25 yards, superb, bragging superb.
I know Colt is in bankruptcy, but I wouldn't hesitate to buy another.
