Internal Locks (IL) on a slow Sunday
With the info gleaned from this forum and youtube, I took three revolvers ( Gov, 21 and 27) apart, removed the internal locks, cleaned a little, reassembled correctly and dry fired. All are good!
A trick no one mentioned that I'd like to share: Putting a small wooden wedge between the frame and the main spring takes the pressure off the strain screw, making the loosening less of a tweek for the initial turn. Just saying...
Might send off for the plugs now!?!

Thanks for posting that. I have to change a firing pin on my 627 and I figure that, since I have to disassemble the revolver, I might as well do the IL removal at the same time. If you found any particularly helpful Youtube instruction video...could you please link it here? There are quite a few of those videos, enough that I don't have time to watch all. Larry Potterfield of MidwayUSA makes some great how-to gunsmithing videos...but I'm almost certain he doesn't, or won't show a lock removal.

I will look for the better video. I'll post. When you get the side plate off, take a picture to refer back to later. YouTube

Here's a link for lock removal, tear down, and reassembly
Takes an eyeglasses screwdriver and a tooth pick to pop the locking cam out in a couple seconds

Thanks Bob I'll stay tuned. Thanks JDinAz....LOL I found that one last week while browsing on Youtube and thought it worthy of saving in my bookmarks for future reference.

I personally have started pulling the flag, which actually locks the trigger, and leaving the lock itself.

I did a couple of my guns and have more plugs. To me the only hassle is getting the plug lined to slip in the hole. Perfect fit and square shoulders. I used a dental pick on the fork to slide it back.

Put a plug in one today, definitely tough to keep the plug rotated correctly.
Plug sits a little recessed, not satisfied with it, have two more to install. I'll share an opinion after.
Put two more in tonight. They sit just slightly recessed. They fill the hole and the bluing is good. Maybe I am being to picky. Revolvers look great.

I, like dr. mordo, remove the flag and leave the lock.

I wouldn't leave the lock and pull the flag.
It makes it look like a working lock. Does the lock turn, even if the flag is missing?
Would that give someone the impression the gun has a working lock, while it doesn't?
I also wouldn't grind the nub on the flag - same issue.
If you don't want a lock, remove it, plug it (or not) or buy a gun without one.

That's a great idea. Some heavy duty grease once in awhile via the Zerk fitting.

Lightening holes.
Drill them all over the frame.
Shed grams from your heavy revolver.
Best,
Rick

I have heard of the lock working loose after removing the flag and jamming up the works if left in the gun.
The best thing is to remove the lock and live with the hole or install the plug.

Thread revival.
I recently purchased a 686 with the lock and I'm going to leave it intact. My reasoning? It hasn't locked up on it's own yet and the thought of having that wide gap near the hammer where the flag is supposed to be doesn't thrill me much. I don't even notice it has a lock when I'm shooting it anyway.

I wish they made something that filled the lock hole and flag slot. Until then I’ve left them stock.

THANKS FOR THAT USEFUL TIP.......
ALLOW ME TO GIVE YOU AN IMPORTANT TIP, IN RETURN. SAVE THE IL HARDWARE THAT YOU REMOVED. IF YOU EVER NEED TO SEND ONE OF THOSE GUNS INTO THE FACTORY FOR REPAIRS, YOU WILL NEED TO REINSTALL THE PARTS BEFORE YOU SHIP THE GUN......
OTHERWISE, YOUR WARRANTY WILL BE VOIDED. YOU WILL BE CHARGED FOR SHIPPING BOTH WAYS, AND PARTS AND LABOR TO MAKE THE REQUESTED REPAIRS. IN ADDITION, YOU WILL BE CHARGED THE COST OF A NEW IL, AS WELL AS THE LABOR TO INSTALL IT......
I FOUND THIS OUT THE HARD WAY WHEN I SENT A PLUGGED NEW M617 IN, TO RESOLVE THE PROBLEM OF IT SPITTING LEAD....

S&W internal flag locks
Thank you for an informative thread
on the Pro's and Con's of the "S&W
internal flag lock".
I have two Revolvers with the "Lock",
a 637 38Spl and a 629 MG 44Mag.
Never had a problem.
I see it this way, S&W Revolvers with
the "Lock" will just be the next Phase
of collecting S&Ws.
Plus the "Lock" is great if you have
adventurous small children around.
