so in theory, it might be possible to have a 10shot cylinder retrofitted to a OM or NM convertible, so 3 total 6 shot 22lr, 6 shot 22mag and an extra 10shot.
just my thoughts. anyone else have any thoughts/opinions on this.
Your lock work would have to change as well. The lock work on a six shot turns the cylinder one sixth of a turn and a ten shot would turn it one tenth of a turn. Not simply a matter of dropping in a different cylinder.
