J frame/revolver experts - lubrication

View · by **purd0027** on Mon Nov 14, 2016 7:37 pm

Hi,
I've got a 637 that I'm comfortable cleaning externally but I had encountered some sticky trigger issues after about two years of daily pocket carry. I've disassembled the firearm (removed grip, crane, cylinder) and have blasted it with Gunscrubber cleaner and scrubbed the parts with a brush. Drying now and hope this will take care of the issue (although I was expecting a lot of lint/grit, etc. in the mechanism it seemed pretty clean).

I've never been clear regarding which parts need lubrication and how much. Can anyone enlighten me? Thanks!

Look at your areas of metal/metal contact. If it slides, grease it, if it rotates oil it.

Sticky trigger?

Yes, the trigger required non-linear pull in double action, almost like it was binding up. If I drew the hammer back with my thumb it was okay.

I've had a J-frame 642 Airweight for many years. Very convenient to carry around, and a very simple self-defense tool. That said, I hate that little gun and shoot it only enough to be reasonably proficient. The OOB trigger was bad, so I installed an Apex Duty/Carry kit, also took the opportunity to scrub the relevant parts with some Flitz. Made a YUGE difference in the trigger. My son has one in his as well, neither of us has had any ignition problems.

What is "OOB trigger"?

The Apex trigger kit for the J-frame is like $25. As a percentage of the total investment and in terms of bang-for-buck, that kit is an excellent expenditure.

Here are my two cents worth of advice:

I will occasionally place a drop of oil on the ejector rod (not on the ejector star) and will put a dab of grease on the yoke shaft. Key word is a drop- as the ad slogan goes, a little dab'll do ya...... Work the ejector rod and spin the cylinder a few times, then wipe off any visible excess. Most problems that people seem to have with revolvers are due to over-lubrication. Mix oil, heat, spent powder, and lead --- and you can get a gooey sludge that expands beneath the star and pushes it rearward. Then the cylinder gets stuck. Very small amounts probably won't be a problem, but lots of folks overdo it.

If I am removing the sideplate for some other reason, I will place a drop of oil on the bottom of the rebound slide and on the hammer and trigger pivot pins. However, I believe that S&W revolver lockwork was designed to work with minimal lubrication, and that excess oil will just attract dirt and eventually gum up the works. For that reason, I advise against blindly squirting oil into the hammer recess, around the trigger, etc.

Also, any oil that goes into revolver lockwork should be the kind that will never dry up and leave varnish; you should use high-quality synthetics and avoid cheap generic products like WD-40 or 3-in-One.

I just purchased the Wilson combat kit for my j-frame. Haven't had time to work on it, but I was hoping to polish a few things while in there. I may just start with the springs though. This thread is helpful to me, so thank you everyone!

I have an S&W rebound slide spring tool, it makes installing a new spring slightly easier (it is still a PITA). If anyone would like to borrow it, send me a PM.

You did not take the side plate off? If not, search youtube for the process as that probably needs cleaning as well.
