I have recently bought a brand new 357 Blackhawk in stainless steel. I have been looking around regarding getting different grips for the gun. Is there any specific information that I need to state when ordering new grips. I have read there have been different grip frames for the Blackhawks over the years. So I just want to specify my gun correctly so I get grips that fit the first time. Any good recommendations for places to get grips? Any hints on fitting them or are they pretty standard and changing them out is pretty simple? This is my first single action revolver. Thanks!
