Henning flat trigger

[AlphaSeeker]

Purchased the Match about 3 years ago as a 45acp.

Have been running it with a 9mm long slide conversion.

Installed the Henning flat trigger [medium] and tuned it for shortest travel.

Henning trigger and a F/O sight are my favorite mod to this gun.

Everyone who tries the trigger loves it.

When I reinstall the 45 from time to time, the hammer does not always reset.

I can cock it by hand and fire the round. This happens once per mag, sometimes more.

Would hate to readjust the trigger since most of my current shooting is done in 9mm.

Any thought on tuning are appreciated.

Issue was not present until the new trigger was installed.

Did notice that the 9mm showed similar behavior if the pre travel was too short. I had to allow for a bit more pre-travel for the 9mm to run 100%.

When you say the hammer does not reset, are you talking about the hammer falling forward after the shot? Or are you saying the sear doesn't reset (ie you pull the trigger and nothing happens)?

Hammer falls forward

[Nealio]

Could be that the sear is rounded and the bigger round is causing enough of a disturbance to make it slip?

The upper should not effect the trigger, reset, etc.

I thought the same but it worked very reliably with the oem trigger.

after dealing with some of these issues with my limited and henning trigger, your right it shouldnt effect just by changing the slide but when i put limited slide on my match frame had the same issues and had to re adjust the pre and over travel screws to get it to run smoothly..

nealio helped me out a few times with such issues as the over travel screw would come loose and not let hammer fall completely basically half cocked
