I'm a school teacher and LEO. I qualified on my S&W M442 today, using Speer 158 grain +Ps. One word sums up the experience: OUCH!!!
I've been 'playing' with some 110 grain JHPs(it's a Remington HP) loaded by Anderson's Munitions, out of Memphis, TN. They are accurate, reliable and MUCH more pleasant to shoot, which, if using a snubbie .38, is something you should be doing a LOT of.
I recently saw Winchester's new 130 grain SXT +P load for the .38SPL. It looks 'interesting'.
