I have the R8 and it is by far the best handgun/revolver I have ever owned. I can hit clays at 25-40 yards easily, which says a lot because I'm not known for my accuracy. I can even do it in DA.
I put a TLR-1 on it and it complements it well and hasn't failed yet and so far I have put 400-500 rounds through it, all .357 loads. The recoil is very manageable and I can shoot it for 2-3 hours and not feel worn out. My other revolver (M&P 340) with .357 loads isn't as nice
, 10 rounds and I'm pretty much done.
Trigger pull is lighter and smoother than my 340. I had an LCR and the trigger on it was better, but it was DA only. It is front heavy but I think the extra weight out front with the light helps.
It's a unique gun and well worth it if you're going to invest in something like it. You'll have a hard time finding a holster out there that accepts a light mounted as well, which is why I'm going to do my own.
Hope this helps you a little.
