SW Revolver Cylinder Stop Spring / Engagement

SW CQB 45 · Sep 11, 2015

I use a 4" L frame for competition.

for years I got used to a 686 that was tuned by Bob Jones and the timing is perfect with a positive engagement for the cylinder stop. in other words, I got used to when the hammer was about to "break".

I parked that gun last year due to an egg shaped center pin hole which was causing the cylinder release to lock up every now and then. My year long waiting list for Cylinder & Slide is currently at 1 year and 9 months. I call them next week to see if they are caught up to the point where I send my 686 to them.

Anyway in 2013 in anticipation of putting down my Bob Jones 686 for a while, I had a 586 built by another smith. And while the revolver is accurate, the cylinder stop engagement is soft or faint compared to what I am used to.

Question:
would replacing the cylinder stop spring with a heavier one improve this felt engagement?

if so, do they make one? (I looked online and was unable to locate one)

if there is not the case, would increasing rebound spring rate give a more positive cylinder stop engagement? I was detailing cleaning my revolver and noticed a very light rebound spring.

TIA

Does it carry up properly?

Wolff does make what they refer to as an "extra-power" cylinder stop spring for the L-frame. You could try one in the gun to see if to get a more audible "click" when the gun carries up.

If you are able, check for excess lubricant or residue around the cylinder stop, and check the stop slots for debris. (look at them with a magnifier if you have one) Shooting debris, excess lubrication and crud in those locations can interfere with both the sound and feel of the stop locking into place.

Dawg gonit

I detailed the internals and put TWB25 thick lube on the stop.

I will clean off that lube and replace it with regular oil.

Yes, the gun carries up correctly.....just a very soft last click.

Thanks.....I will look into that spring.

WOW! You've got a lot more patience than I would have! 1 year & 9 months - - - - crazy! You would THINK they might want to hire another Gunsmith or two!

there is very few that I found that will perform that service (machine and install new center pin hole bushing). I decided on them since they have a reputation. that is the reason I had another L frame tuned up, but Jones wasn't doing anymore guns.

Plus I have a $50 deposit down to hold my space.

I have extremely large hands and fingers. I get made fun of a lot by co-workers on the size of my hands.

My Bob Jones Lframe audible and tactile felt clicks as I worked the trigger were music to my ears and fingers.

The gun I have now, works great…..just lacks the music.

it seems that my click is less pronounced since I added the thick lube…..I am just going to dab it off on the cylinder stop with a q-tip.

Your thick lube may be the problem. A thin lube, such as Break Free and very little of it would be best.

Hello, Does anyone know a good step-by-step installation graphic or video to install this cylinder stop spring?

Hondo44 · Sep 2, 2018

Yes! If you jave a 3 screw K or N frame. Otherwise, if you have an I frame from the late 1950's, let me know.

Go to the 8 min, 59 seconds point of this video:

Sorry...I guess that would HELP! I have a Model 586 (N frame) Blue 357 mag Revolver. I just purchased this revolver in July, 2018 and admire the engineering, look and feel. I do not like the inane "Clinton-Lock"

Your 586 is an L frame. I bet you knew that.

That video will still work for you however except for the Clinton-lock parts.
