All the Tx22 suggestions... I guess you didn't catch it, that is NOT on my list to buy, it is the .22lr handgun
I currently own. It has helped awaken an interest in .22lr pistols, originally buying it because it was inexpensive to use for cheap practice with .22lr, but I'm really enjoying the gun. It helped inspire me to finally buy the S&W 317 from this thread, and I'm still considering the Glock 44, Beretta 92, 1911 (probably Walther to keep costs down), maybe the Wrangler, but with the rebate the Heritage Arms has become a strong contender (hard to beat a handgun around $100). Unfortunately, I can no longer say my Tx22 has been 100% reliable (after somewhere between 750-1000 rounds), Taurus autos apparently still can have an issue with the rear sight screw and mine disappeared (I was still able to shoot it, I just had to move it towards the center with my thumb every mag or so). Easy fix, I've ordered another for $2 online, I'll use Loctite when it comes so it doesn't happen again, and while I was at it I ordered a front night sight for my Taurus 856 revolver to make the shipping worthwhile. For years I was on a carry gun kick (even though, living in MD, I could only carry when out of state on my UT non-resident permit). I guess, even after the minor glitch, the Tx22 may have awakened a rimfire kick for me (I'm also thinking I may want a .22mag revolver soon as well- or maybe the Rough Rider with the interchangeable cylinders).
Of the list, the G-44 or Kadet kit is where I would go for your next .22.
The 317 is not a “fun” gun to me, mine has a rimfire trigger pull ( rather hefty) combined with ultra light weight ( not easy to steady against the trigger pull) and hi-viz front/V notch rear sights on a 3” barrel (not conducive to fine accuracy), so it is work to shoot rather than fun. Mine is more of a backpacking companion than a true fun plinker, let us know what you think.
The wrangler is ok, I have the black 4.25” and a 3.5” birdshead. The longer barreled model is pretty accurate, but the hand failed and it had to go back. I put in a reduced power trigger return spring in the birdshead and the trigger pull is much improved over stock.
The G44 isnt a target-grade gun, but it is a great stand-in and trainer for any of my double-stack Glock pistols. (If they just made a G-48 sized one!)
The CZ 75-series is my newest favorite. A Kadet would be a great stand-in, too!
Let us know how they shoot when you get a chance .
Stay safe.
If the 317 ends up not being so fun due to the trigger (I'm familiar with rimfire DA revolvers having heavy triggers due to the heavy springs needed to reliably ignite the rimfire primers), that is fine, though it will be a disappointment. It will largely be a trainer for my 2" and 3" revolvers, and with the weight, may sometimes be carried as a backup gun.
The Wranger still interests me, but with the rebate putting the Heritage Arms options at about half the price, if I go SA revolver, I'm leaning Heritage since they are both budget guns anyway. If I go more expensive than the Heritage, I'll probably spend more and go for a Single Six.
The G44 and CZ Kadet would serve a similar purpose, though for that purpose I'm slightly leaning towards the Glock. The PCR and P01 have long been among my main carry guns (when out of state). Before I got them, I had 10000-20000 rounds through my full sized CZ 75B. The Glock 19 is new to me (right around 1000 rounds plus or minus a couple boxes of ammo). While cheap .22lr practice out of my CZs would be nice, I already shoot them very well. Like many, the CZ 75 grip angle and grip thickness feels like it was carved out custom for my hand, and I shoot it like it is a natural extension of my hand. It isn't that I'm a poor shot with the Glock 19, but with 1000 rounds plus or minus a hundred or so, it isn't the same. Meanwhile, with the slightly smaller size and noticeable weight difference, I suspect that the Glock 19 will probably end up with a lot more carry time now that I'll be carrying nearly everyday. So, the trainer in a Glock that was purposely designed to be around the size or a G19 may make more sense.
