Mine comes on and off easy enough. I just put it in a vise and it comes off. I put a small amount of grease on the threads and screw it back on.I had the TX22 and while it shot nice it made me so mad I sold it off. Tried to remove the thread protector so I could run my suppressor. It was on so tight that even with a little heat I had to ruin the thread protector to get it off. Should have known better with a Taurus product but wanted to give it a chance.
I have over 30 .22 handguns. I shy away from the expensive models because they tend to be ammo picky. I have Smith, Ruger, Glock, Sig and Beretta in Semi Auto. I am a mag hoarder so I also tend to stay away from anything that I cant get mags readily for.
