[TWD] Why did Rick use a revolver as his police sidearm when all of the other officers used pistols?

* It also seems like an odd choice as a service weapon given how pistols had largely replaced revolvers as the police officer’s main sidearm.

He's a small-time sheriff in rural America, his department probably doesn't have a standard issue sidearm and he likely has to buy his own gun with either his own money or is compensated by his department, so basically he can carry whatever firearm he wants. In this case, it's a Colt Python in .357 Magnum.
