Colt D frame trigger reset

[MagicD]

My pre 74 Cobra has trigger reset problems. Action and timing are fine but trigger reset is very sluggish, it feels sticky and sometimes won't reset unless trigger is very lightly pressed forward.
Could this be a cleaning issue or is spring replacement required.

Should an average kitchen table smith mess with this?
We are talking in appearance 98% condition old revolver.

Your Colt doesn't have a trigger return spring exactly.
At least, not in the same sense that a S&W has a rebound spring.

They operate off a part of the big V-Mainspring that also powers the hammer.

If you are not getting misfires from a weak mainspring, I seriously doubt it needs anything other then an oil change.

I'd take the grips off, then hose out the innards with WD-40 or gun scrubber while working the action.

Then blow dry with compressed air, and hose it out again with Rem-Oil.

Then blow that out.

What you can't blow out should be just right for lube.

I would not recommend anyone taking a older Colt apart without prior experience doing it.
Or at least have the Jerry Kuhnhausen book in front of them after you have read & studied it from cover to cover sixteen times.

My compliments to you.
Did as you described and used penetrating oil after solvent. Major improvement which culminated in total success with penetrating oil in area lateral to the hand easily reached with cylinder open.I could see this moving part get hung up in what should be a vertical movement ,it appears part of the tigger assembly.
Now moves as slick as sh*t through a goose. Once again thanks.

Volume I of that book is shockingly good.
I can't imagine Kuhnhausen being smart enough to write that on his own.
The Colt factory must have helped.

I can't imagine Kuhnhausen being smart enough to write that on his own. The Colt factory must have helped.

He ran, among other things, a warrantee repair center for a number of manufacturers, so he was pretty smart in his own right. But you are right that the Colt factory provided him with material they used to train they're own employees.
