My EDC consists of a Model 38-0 and a Model 638-1. Both are equipped with CT LG-405 laser grips which have an air chamber built in over the back strap that helps cushion the recoil:

I've unfortunately been blessed with arthritis in my hands and wrists, so shooting these little Airweights can be, uh, stimulating. The LG-405 grips help make this manageable, as does my use of standard velocity ammo. Plus, they are a boot grip size, which helps with concealment.
Good luck,
Dave
