The pressure for the 45 Colt ( with out looking it up ) is about twice that of the 410 and with a different pressure curve ( shock wave if you will ). You might get away with it far a few shots, but it is like a time bomb that is ticking away. Sooner or later something is going to give, if the shooter is lucky it will only be a cracked frame, if he is unlucky it will a shattered frame or burst barrel. Does he feel lucky?
Very bad ideal, been there done that, know what I'm talking about.
