On the search 22lr pistol for training

Looking for a good training pistol, something optics ready and threaded barrel would be nice.

TX22 caught my eye but I am confused if the standard model comes with a threaded barrel, some posts describe it as threaded but nothing on Taurus website.

The competition model looks interesting but longer than my current carry's. I have a ruger Mark II and a keltec cp33 neither of which is good for training IMO.

Thoughts between Glock 44 (carry a 43x and sig p365xl, Walther PDP C), TX22, TX22 Comp, SR22?
