I use a pair of model 391's and they are quite the work horse where volume shooting is concerned. You can put any type of ammo or load into them and they work all the time.
I agree with you Bob, I haven't found anyone yet that doesn't like there 391. Btw, have you had any dealings with the new Beretta A400 Xplor? Read about it but haven't had one in my hands as of yet.
