M29 44 mag S&W screw on front of trigger guard?

[missed it by that much]

As the title says. Just bought a 4 inch M29 Smith and Wesson in 44 mag. Has a screw in front of the trigger guard below the chin. Just wondering about the function of this screw. I've got lots of Smith and wesson revolvers Just never seen this screw before.

Interesting, I don’t remember seeing one like this.

That screw holds in a spring and plunger that operates the cylinder stop. In later models they just put the spring inside the sideplate without a plunger. That gun is probably from the late 50s to sometime in the 60s.

Thanks Warren. For the information. It'd in great shape and got it for 700 hundred dollars. Couldn't resist. Got to load up some ammo and shoot it.

Often called 5-screw S&W's. Nice pickup for $700.

Yes - great gun. You got a deal on that one.
