1911 problem

[mr.haney]

Ok fellas I need a 1911 guru. Picked up a nice Rock island 1911 45 and 22 combo Saturday and low and behold it has issues. When test firing the hammer follows the slide forward after the first round. It chambers the next round fine but the hammer is already down. You can cock it and shoot the next round but you can also have a surprise discharge as I did because the hammer went forward when released. Could be as simple as the over travel screw being in the wrong position. Help.

Could be a number of things from springs to "gunsmithing" by someone not a gunsmith.

There's a few tests you can do to narrow down the cause but I don't know where to tell you to find them off the top of my head. Search for '1911 hammer follow test' and you'll find more information than you care to.

Highly recommend take it to a gunsmith, maybe request a new drop in trigger from “Cylinder and Slide” company. I wouldn’t load any live ammo in it until it’s repaired.

Is it new or used?
With the gun UNLOADED, cycle the action to see if the slide brings the hammer to the full cock notch. Like previous posters said could be several things and also has someone been tinkering?

It’s a used gun and a set of sear springs was in the box so I’m sure it was tinkered with.

It will come to full cock position

You’re right on track. It’s probably either the sear spring doesn’t have enough tension on one or more of the legs of the over travel screw is too far in.

I took the over travel screw out and it locks back part of the time on not other times. Doesn’t seem to be a half cock. I’m thinking sear spring wrong.

Is this the same 1911 you posted for sale yesterday with an upgraded trigger?
