Own a TRR8 and M&P R8. My favorite revolvers, hands down, for action, balance, weight, capacity, accuracy. Versatile. M&P has a permanent lower rail, so Simply Rugged made me a holster that would accommodate that. Prefer the TRR8 sights to the M&P R8.
Narrow stock grips handle .357 Magnum loads without pain up through 550 ft. lbs. of energy. Past that get some big wooden Hogues and you can shoot virtually any load comfortably.
They typically deliver with fairly heavy action. My TRR8 went to TK Custom for an action job.
The R8's are the best S&W revolvers made, and for the money, arguably the best revolver period. Korth/Nighthawk Mongoose is the only revolver I prefer to the R8's, but they're $3,499.
1. TRR8 with Hogue wooden grips, Aimpoint optic, and Speed Beez holster. Speed Beez can not be used with the M&P R8 due to the permanent lower rail.
2. M&P R8
3. PC TRR8 with all rails removed laying next to weapon along with a PC 627 UDR and PC 586 L-Comp.
4. Extreme accuracy due to shrouded barrel design. Two shot group at approximately 70 meters from a tree stand with optic and rest. Federal Premium Barnes .357 Magnum.
