I had the exact same experience. Those super light 357s are great to carry but they're for emergency use only! When I was young and stupid(er), on the 4th of July some of my friends and I would hold one of those little Ladyfinger firecrackers in a tight fist and let it blow in our hand. I had almost forgotten about that until I felt the exact same sensation shooting that Airweight.
I really like my Ruger SP101. It weighs, as I recall, 29 ounces, versus about 12 ounces for some of those scandium alloy guns. Shooting full power 357 from the SP101 with the stock grips is uncomfortable but not too painful. I bought the rubber Hogue monogrip and with that, the most blazing 357 ammo is no problem, and any .38 Special is totally comfortable.
And yeah, a spurless or enclosed hammer is the way to go for a defensive revolver. Not so much because of the snagging issue, in my mind, but more because if you're gun is DA only, then you're forced to actually practice DA shooting whenever you take it to the range, and you'll get good at it. If you have the option to shoot single action, it's tempting to do that when you practice.
