Terry,

You didn't mention what make it is. Most 1911 variations will require a minimum of 200 + rounds to break-in. A very good friend who used to custom build 1911s said that he never determined how accurate one was going to be, until he had fired at least 200+ rds through it. He built some very high end beautiful custom 1911s. If accuracy wasn't up to his exacting standards, he would tear it down and start over.

In addition, if you haven't shot a 1911 much, it takes some getting used to and adjustment to fire them accurately. Much the reason a lot of GI's thought they were inaccurate rattle traps, which they are not. Once you learn to shoot them.

An arched or flat mainspring housing, short or long trigger, can also effect how you hold them, in turn effecting accuracy depending on the size of your hand and length of your fingers.

The two most critical accuracy points on a 1911 are the barrel link length, and barrel bushing, the third being how tightly the slide is on the rails. Adjusting the link and the bushing often negates any discernible slide play on the rails

When the slide is closed, firmly press down on the top of the barrel hood (chamber) with you thumb. If there is any downward play or movement, a longer fitted link is needed for better accuracy. The barrel bushing should fit the muzzle snugly, with as little radial play as possible.

As far as being dirty. That depends on what type of powder the ammo was loaded with. Some powders burn clean, others burn like coal in a steam engine.
