1911 question

[johnds]

I shoot a Les Baer p2 and it has worked fine since new. It had a trigger pull of about 4.5 lbs. I wanted a lighter trigger pull for match shooting. I bent the left fork of the sear spring back just a little to reduce the trigger pull. I ended up with a 3.0 lb pull. The problem is that if I rack the slide fast with my finger off the trigger, sometimes the hammer follows to the half cock position. Yes, I know that is not good for the trigger job. If I rack the slide while holding the trigger then this does not occur. My question is: Is there something else that could contribute to the hammer following the slide down to the half cock position besides the fact that I bent the spring? Somehow someway this happened during a match this weekend during a mag change. I was thinking that this shoud not happen when loaded because chambering a round should slow the slide down enough to preclude the hammer from following.

You reduced the sear spring tension more than the engagement could stand.

If this is strictly a bullseye gun, a lot of old timers would hold the trigger back as they loaded the gun to prevent hammer follow. Not recommended for action shooting like IPSC.

Since it doesn't happen with your trigger held back that would indicate that you are experiencing trigger bounce and should increase the tension on the center leg of the sear spring.

I had an extra new hammer that I installed just to see what effect that would have. The problem went away which would seem to indicate that the was something not quite right in the way the sear and hammer were interfacing. Before I had installed a new sear spring and that did not change anything.

Thanks for the ideas folks,

for what its worth,
