Even with a wheelgun, Snowbird, I'd want to have a couple hundred rounds through before carrying it. Over the years I've seen:
-- Revolvers that locked up when the cylinders heated up from .357 rounds and the gas ring expanded;
-- Revolvers whose firing pin bushings were the wrong size, allowing primer flowback to lock up the gun (usually involving very hot loads for the caliber);
-- Revolvers that would sieze up as soon as the list bit of crud got under their ejector stars from only a little shooting, or from particularly dirty burning ammo.
If it's made by man, bro, it can fail and needs to be checked out.
