I wish I had started shooting .22lr earlier. I believe I would be more proficient if I had. I remember the Colt .22. A friend let me take his for a spin around the target, I recall it being remarkably accurate, even in my hands. Beretta makes the "U22 Neos" that I believe is the same gun as the Colt with a few changes in the safety and takedown method. The Beretta also has the very steep grip angle of the Colt. I seem to recall the Colt grip being more chubby than the Beretta and it fit my hand better.
https://www.beretta.com/en-us/u22-neos-inox/ The Colt and Beretta are so similar that this guy shows the magazines are interchangeable.
I had an opportunity to buy the Colt at a discount when I was an instructor years ago. Hindsight, how about that?
One of my current Handguns is this little wonder. Styled after the Colt 1911, it has all the controls in a similar location as the Colt, minus the Grip Safety.

The Sturm, Ruger & Company, 22/45 chambered in .22lr. I attribute its amazing accuracy to it's construction. It's a tack-driver in anyones hands! You would have to put in a lot of effort to miss the target with this Ruger!
My absolute, hands down favorite .22s are not guns at all. They are conversion kits.

From Top to Bottom, 1911 Full Size Target Model, 1911 Commander Length, and Glock Full size for 17/22 frames.
There is a subtle difference in weight, more noticeable with the Glock conversion than the others, but trigger time is trigger time after all. After owning the Glock conversion for nearly 20 years it has started to fail on extraction. It might be time to clean it again, maybe it needs an extractor spring. I like these kits for several reasons.
1) They are only "Parts", therefore no paperwork or waiting periods, (I live in CA, waiting periods are 10 days). So, they are "Cash and Carry" or, order online.
2) You are converting
your gun. Same trigger feel, identical operation. They lock open on an empty magazine, like they should!
3) Cheaper than a full on gun in most cases.
4) Less than a minute to convert back and forth.
5) Only a little temperamental about ammo. I prefer CCI Mini Mags, but they do work with some other flavors. Your milage may vary.
Kits are available for 1911's, (including some wide bodies) most Glocks, and some of Springfield Armory's XD line. You can find them here:
Advantage Arms Conversion Kits @bc45,
Nice review! I would consider one if it were available in California!
