Smith TRR8 vs. R8
I'm on this because I just bought a TRR8 and had to do my research to decide which one to buy.
Both models are considered tactical revolvers. Both are 8 shot, both are scandium frames with steel cylinders. Both have separate steel barrels which are covered by a scandium shroud.
The R8 has polygonal rifling, the TRR8 has broach rifling.
The R8 has a permanent light rail, the TRR8 has a separate light rail and a separate scope mount which come with the gun and attach with supplied screws.
It took me a while to realize (after watching Nutnfancy's youtube test report [ame]https://www.youtube.com/watch?v=Sb_GFV_0KY8&feature=youtu.be[/ame]) that both of these revolvers came about as a request by law enforcement to produce a tactical entry revolver that could be used by the point man holding a protective ballastic shield when executing a SWAT entry.
Eight shots of .357 Magnum is a lot of firepower and a real man stopper. Both revolvers are high performance weapons made by the Smith & Wesson Performance Center and have honed actions. The scandium frame is actually a small component mixed with aluminium to produce a strong , light weight tactical weapon.
I also acquired the stainless steel 8 shot .357 Magnum V-Comp
which is a more competition oriented revolver. 10 ounces heavier, but also a Performance Center product.
Smith & Wesson is still producing well designed products which are worthy of owning and shooting.
Just my two cents.
