I recently bought a nice 19-5 that has Pachmyer grips. I am thinking of putting a set of factory correct wood grips on it. Where are they usually found, and what do they cost?

On the ammo, I know its not recommended to shoot 357's all the time in a 19, so I plan on shooting 38 spl in it. The most common ammo I find locally is 100 rd boxes of Remington 38 spl+p 125 grains at Walmart. Is it OK to use alot of 38 spl+p?
