Picked up the 500 pistol grip online for $340
I wasn't happy with the hard plastic factory grip when I got it. Took it out today for some trials with different loads, 8 bird shot, 5 and 00. (ouch!} It only reassured me to change the grip because my wrist was hurting by the time I left the range. It just did not ergonomically fit me so I ordered a more cushioned, Hogue grip today with a better fit angle for $25 with free shipping.
