I was thinking of getting a Walther P22 but after reading some reviews, turned out Ruger SR22 is much way better. My question, i only found Twin Tech tactical threaded barrel for it. Any other makers out there? http://www.twintechtactical.com/SR22TBK.html And i noticed the thread size is the same as my Glock 19. Which means will i be able to use my SWR Trident9 on the SR22? Has anyone done this, using 9mm can on .22lr host? I'm aware my can is not a user servicable. Thank you.
