repair of 1926 Colt Police Positive .22

Hello out there! I'm a new forum member and I joined to get help in finding a gunsmith to repair the timing on my old .22 Police Positive. It is in good over-all condition but has too much cylinder play in lock-up. I'm an old guy who loves old Colt revolvers and like to shoot them too. I need to get this one in firing condition again. Any suggestions or advice is appreciated, Thanks to all! Dennis

The Colt factory will no longer service Colt's that old.

However, Frank Glenn is a Master pistolsmith who's well known as a Colt expert.
He does Colt repairs to Colt factory standards and specs.
He's done a good bit of work for people on the Colt Forum and gets universally excellent reviews for quality of work, turnaround, and price.

Unless it's pretty wrecked he can restore it to factory spec condition.
Unless there's something else wrong, all that may be needed is a simple refit of a single part to correct a timing issue.

You might check it for cylinder end shake to insure that's not also a problem, which is common on older guns, not just Colt's.
To check cylinder end shake, push the closed cylinder to the rear and hold it there while you use a automotive feeler gage to gage the gap between the rear of the barrel and front of the cylinder.
(This is also the actual barrel-cylinder gap).

Then push the cylinder forward and hold it there while you gage the barrel-cylinder gap again.
Subtract the one measurement from the other.

To be in spec a Colt is required to have NO MORE then 0.003" end shake.
If it's over 0.003" the cylinder needs repairs. Otherwise every time you fire the gun the back and forth cylinder movement will hammer the frame to death.
If your Colt needs excess cylinder end shake repair, Glenn can do that too.

Does Mr. Glenn have anybody working for him, learning how to do these repairs on Colt double action revolvers? Be a true shame if the knowledge was lost in the future. (I have no idea of Frank Glenn's age or health, just saying.)

I have no idea.
Email him and ask.

If you do, let us know what he says.
