5 screw S&W K frame LOCKING BOLT

[ccnv]

Is the locking bolt on a 5 screw K different than a current bolt? I have one that needs replacing.

If you are correctly referring to the plunger in the barrel lug that secures the front of the extractor rod, then current the parts will be correct for your older revolver. The locking bolt and the bolt, you used both terms, are very different! The "bolt" is within the frame and the thumbpiece attaches to it. The plunger unser the barrel is the "locking bolt".

The bolt within the frame that locks the cylinder in place.
