S&w 642 - Trigger Pull got much stiffer. What's wrong?
I got my 642 three weeks ago and so far have shot 150 rounds. Trigger pull is heavy DAO but very smooth and crisp. I also use snap caps to practice dry firing at home (done over 300 pulls so far).
While practicing dry firing today, the intial trigger pull became very stiff (not as smooth as it was). I suppose with dry firing, the trigger will become smoother.
Don't know what happened. Could it bcz some dirts (metal debris from shooting) got into the gun? Any maintenance or cleaning I need to do?
I plan to use the gun for CCW so I don't want to do anything to comprise its reliability. FYI, I called SW customer service. They asked me to send the gun in for check up.
It's a brand new revolver. I was a bit disappointed after shooting it 150 rounds. What could be the problem?
Thanks for your help.
It could be that something is binding up the cylinder or debris in the trigger mechanism.
If S&W is willing to look at it, send it in.
My 442 froze due to a 1/16" thread fron a cleaning patch, found it with a good look and a can of compressed air, no disassembly required. YMMV.
My 642 is back to normal - relief but why?
The proper dry firing sequence should be 5 shots with breaks (to simulate change of ammo). They said using snap caps and dry fire continously will make the revolver drag on them. The finger muscle will become fatigue and feel stiffer trigger pull while the trigger pull on the 642 does not really change.
In other words, shooting real ammo is different from practicing dry fires.
I'll shoot at the range this week and see what happens.
Does this make sense to your experience?
