There had been some shooters using them here in Manitoba, but not for a few months. It came up for sale actually, and I did look at it as an entry into open division. When your behind the gun, like most, you don't "feel" that blast. Just don't be the RO indoors when shooting with barricades all over the place. As I said, the shooter won't sense it, but you'll punish the hell our of everyone else. I would have told everyone else to just use plugs AND muffs, and to get over it, but I decided to go .38 Stupid instead. Also, you don't need to go insane with 180+ PF just because that's what the gun was originally designed to do. The .357 Sig I tested was the loudest thing I've ever heard and was only running at barely 170PF. Use what is safe and what you can afford. Everything after that is a bonus.
