I have a S&W 686-1 with a orange plastic insert on the ramp. I'm sure many of you are familiar with this typical S&W set up. My question is this: is there an alternative insert for the dovetail slot? I found a Meprolight sight set up that says it's for the red ramp front, does this mean it with fit the 686? It's a tritium lamp and from the picture it looks like it might fit but pictures can be deceiving.
Thanks,
