Colt OMM .22 Magnum

OK, I guess if this keeps up, I'm going to have to admit to being a collector of Colt revolvers. I seem to be spending about as much time over here lately as I do in the Semi Auto section. I believe this to be a "1960"….S/N 788xx. A little honest muzzle wear and some on the high spots but overall in very nice shape.
No box or papers :bang_wall:

Great bunch of guys on this side of the fence too. Very nice OMM and in the rare .22 Magnum caliber. Thanks for posting.
Confession is good for the soul.

That's a very nice example. Thanks for sharing.
Thanks guys…I've been here a few times before :) they are good people!

In trying to learn a little more about this pistol, I read this on Wiki…so it must be true :)

The .22 WMR was introduced in 1959 by Winchester, but was not used by Winchester until the Winchester Model 61 slide rifle could be chambered for it, in 1960.[SUP][2][/SUP] By that time, Smith and Wesson and Ruger had revolvers for it, and Savage had come out with the Model 24 and since late 2012, the model 42, a more modern update than the 24, a .22/.410rifle. It was the only successful rimfire cartridge introduced in the 20th Century.[SUP][3

[/SUP]Did Wiki snub Colt? It appears that the OMM in .22 WMR was produced in 59 and 60, at least those are the only years I have seen them in so far. Would that make this handgun the first firearm to use the new cartridge from Winchester ?

I do not know when in 1959 the .22WMR cartridge was introduced, but my OMM .22WMR shipped December 29, 1959. (I did not ask for a build date when I bought the letter years ago.) I do remember reading about the new cartridge at the time, and I could probably find the original gun magazines in my collection if I took the time (and 1959 was not one of the years that got ruined when a water line got a pin hole in it and sprayed them for days before I discovered the leak. So much for copper being a "lifetime" water line!).

Wiki is not a preferred source for accurate gun information. Except for the last sentence, the quote is verbatim from "Cartridges of the World," 6th Edition, 1989. (Later editions after calendar year 2000 may include the last sentence.)

Judge. When you found that water line break your heart must have sank. I can't even imagine the feeling.
True, but my secondary feeling was anger that the small fortune I spent installing all copper water lines did not produce the "lifetime" result I expected. Apparently, I got a bad batch of copper tubing. After a second pin hole under the kitchen sink, I ended up replacing all of that batch to prevent it from happening again.

When I remodeled my daughter's business a few years ago, I used all PEX. It is supposed to last longer than any of us will have to worry about it (but then so is copper!).
