Reinstalling a High Standard model 107 barrel

tclaydon · Nov 2, 2022

Good morning,
High Standard model 107 series.
Gun is in excel condition but has been unused for 50 years. Cleaned and oiled. Tried to reinstall the barrel. Can’t get the barrel to seat. No rust. Pistol is clean. Possible debris in channel with barrel lock and spring??? How do you get the lock and spring off to clean out the channel???
All responses welcome.
Thanks in advance,
Tom Claydon

Not absolutely sure which parts you're asking about. Perhaps include references to this drawing...

Ummm... I think that's the wrong 107.

Part #17 is the barrel takedown plunger Pin. If you must remove the takedown plunger, that's where you start. I wouldn't unless there was no other option to get the plunger working. Try flooding it with solvent while you work it by hand.

Push the plunger in fully. It can be had to do.

Those plungers can be a real b---- to get pushed in all the way. Been there, done that.

If your fingers just aren't strong enough. put the barrel plunger on the edge of a table, push the frame firmly forward and seat the barrel into the frame.
First put the slide on and lock it to the rear.
Put the empty magazine in to keep the slide locked back.

Must be factory part numbers.
I have two of them. See the schematic and parts list here - High Standard Model 107 Supermatic Citation Series Parts (gunpartscorp.com)
Do what @dfariswheel said before diving into removal.

Ah, I sit corrected. This being THR, I simply ass-u-me'd that tclaydon is a fellow studly revolver shooter.

Nuttin' wrong with a revolver. I got a few myself.

Plunger spring is stout, plunger has to be pressed deep.
Edge of the bench is the way to go.
