I have owned a 340PD for many years. I make it a point to get it out for excerise at least a couple times per year. Since all the riot stuff it has been replaced by a P365 but nothing beats the scandium frame for pocket carry.
Although I am not recoil sensitive, I use LG405's laser grips which are thin but probably help a lot on the felt recoil side.
Most of my training is done at 30' and with it's laser grips it is scary accurate at 50'.
I carry 135gr Short Barrel Gold Dots. I do use care when selecting the proper cleaning products (no amonia).
