Hide Out Grips
I just picked up a pair of Precision Gun Specialties Hide Out Grips for my 640. I choose the model HO-4 (finger grooves w/textured finish) for pocket carry purposes. I been carrying a J frame revolver is some way, shape or form for many years and this appears to be one of the better set of grips out there for the price (just over $20 with shipping). It appears that the grips are now manufactured to accommodate speed loaders, as I've read quite a few reviews / articles where the grips had to he trimmed a bit to accept HKS loaders.
