Hammer falling to half cock

Suddenly, the hammer on my 22 conversion started falling to the half cock position after firing. Trigger is between 2-1/2 and 2-3/4 lbs. Disconnector spring is set at 16 oz. Too light? Or something else?

16 oz should be ok if you have everything smooth..

back your trigger stop out a half turn or so.. Also if you have set the pre travel to be tight turn the tab back to allow more pretravel. you need at least .025 pretravel.


if those fail to fix it make sure the disconnector is clearing the sear legs when the slide pushes it down

+1 check your over travel stop. 16 ounces should be enough. I personally prefer 1.25 pounds just for peace of mind.
