I have two 686+ 4" guns, one a dash 4 and the other a dash 6. I'm absolutely sold on both of them. I shoot nothing but hot magnum loads, which they handle without issues. Recoil is easily manageable. Accuracy is superb, which isn't even necessary for these guns since they are strictly home defense weapons.

I'm sure that the SSR is a fine gun also, but I don't own one so I can't speak from experience. I don't like the looks of them, and so for that reason don't plan to ever buy one.

Let us know what you decide and how it goes for you.
