The explosion 40? Kaboom 40? Hopefully that ain't no Glock! Hahaha! Glock bulge!
I've got a g23. I'll rarely if ever use the 40 barrel. I'd rather the 9mm conversion barrel. However I built it so that I can shoot 9,40 and also 22....
But... You should get a 357 sig barrel. 357 magnum performance and same compacity as your 40. That's next on my list.
I have to get another Glock 19 slide if I ever want to shoot 22 TCM. That's a long shot because I still have to get a Glock 21 and Glock 20 slide for my large frame project. Hehe.
Awesome work.
A Sig. 357 is a little overkill unless I'm up against a bear! Nice thing about the 22 is the ammunition is much less expensive!
