Basically what I'm asking is, as per your picture, if you swap the slides around will the guns still work?

OMG your right, haha
i went and got my guns and tried, i swapped the 9mm and 40 both with the 9mm pro core.
the frames are the same on all 3.
the 22 and the 45 have different frames though.
you learn something new every day, today i learned my new things are 2:43am, haha!
Thanks for posting the pics.Is the block in the frame the same on all of them?
