Gents:
I shoot side-by-sides. I know the difference between a boxlock and a sidelock (particularly hand removable), as far as an ability to remove/replace a sidelock that fails, needs drying, or other service.

My question is about sideplates. Do sideplate actions have any inherent advantage over a boxlock? Can you (with a turnscrew) open the action to dry it, rather than pull the stock as you need to do with a boxlock? I'm thinking of an action that has gotten drenched in a downpour or water dunking.
