The lands are .357 apart.
Is modern .38 SPL safe to fire through it? I wonder . . - as long as I avoid +P? I thought the old stuff was easier on the frame and action. The customer service gal at Colt told me based on the serial number, that the date of manufacture was somewhere between 1917 and 1923
“It’s a Colt Army in .38.
The lands are .357 apart.”
I agree with that. If it was a police positive it would say so on the barrel.
Did they call it the ‘New Army’ ? I think that’s the one with those black grips.
“The lands are .357” apart.”
Nope, they’re 0.348-0.350” apart.
The grooves are 0.357”, though.
