1911 hammer falling to half cock

[sammy]

Hello All.

I have a Baer TRS that has around 15,000 rounds through it. It has never had any trigger work done to it, nothing replaced. A shooting buddy picked it up from the table at the range and dropped the slide on an empty chamber which I never do but oh well. Then we noticed the hammer fell to half cock. It has never done this so we tried again and found it does this every other time. I loaded up magazines with only 2 rounds and fired around 100 through it and it never fell to half cock. We checked the trigger pull which came in at 3.8lbs. I happened to have a new mainspring which we replaced and slightly bent the sear spring. Now the trigger is up to 4.5lbs but it still falls to half cock when dropped on an empty chamber.

The gun has not been cleaned in about 700 rounds and the last detail strip was done about 5000 ago. I am inclined to tear it down and clean it but if I am going to send it back I want Baer to see it how it is. What do you all think?

It is doubtful that there is anything wrong with the sear or hammer. The problem most likely lies in the sear spring.

First, determine if it is trigger bounce. Dry fire the gun and keep holding back the trigger. Lock the slide back and then release it. See if the hammer still falls to half cock. If not, then it is most likely trigger bounce. You need to add more tension to the middle finger of the sear spring by bending it forward (just a little.)

If the hammer still falls when you hold the trigger back, then you need more tension on the sear so you need to bend the left finger of the sear spring.

You can do this when you detail strip and clean the gun........since it's about time!

Clean it? What is that?

I did a bit is searching on this and found if the overtravel screw is screwed in too far it will go to half cock. I gave the screw 1/16th of a trun and after dropping the slide 20 times sonething I hate to do it has not happened once. Hopefully this will fix it but if not I will try the center sear spring a bit more.
