I heard a lot about the "ferocity" of .357 loads and the intense muzzle blast in the short barrel when I got my Model 66, but I personally don't see it. I have never minded handgun recoil (not a fan of rifle recoil at all) and love the .44 mag round and if you're that kind of person you probably won't have any issues. There is a noticeable difference between .38 and .357 in the weapon, but I wanted a .357 mag - not a big .38. I mostly shoot .38's to practice, but mix in a cylinder of .357s to stay used to them. Only carry .357s and I'm sure the blast in a confined, and also dark, space would be pretty wicked, but like someone said; that'd be the least of your worries. Just my feelings and like was also said; you can easily sell if if you don't like it. After having a model 66 the only possible downside to the weapon is that it's heavy and large to CCW. I'm kind of slender and with shorts on I have a heavy duty gun belt to make it manageable. I highly recommend the weapon as a concealed carry gun.
