I tried out the polymer framed S&W offering.
Unless you're already a huge ultra-light snubbie fan, I seriously suggest you rent/beg/borrow to try one out first.
It's not even an issue of the recoil, which the polymer mitigates, it's trying to maintain a decent sight picture with that really light weight and the DAO trigger pull is extremely difficult.
If you've already held it, dry fired it, or just a snubbie aficionado in general and have the range time with them, please disregard.
For me, the ability to carry 7 rounds or so of 9mm that's ballistically in the same ballpark, sometimes better than the five .38's or even .357's out of such a short barrel with a little cylinder gap loss too, in a flatter package, with rapid magazine reloads just leaves snubbies making no sense to me anymore.
Unless you don't want to leave shell casings behind.
