More info and photos
Thanks to Webleymkv--measured as you specify, full lock up, the cylinder gap is still 0.011". Yes it is a nickel finish, not chrome; my slip.
Thanks to Duke City Six--I attach photos, having benefitted much from your pointer to the forum info section.
I attach (I hope) two photos of the model 19. One general shot, and one of the breech end of the barrel. Is the "forcing cone" the slightly tapered first mm or two of the barrel? Is the weak point where the metal is thinner because of the flat cut into the bottom of the barrel?
