Umarex Smith & Wesson 327 TRR8 CO2 BB Revolver Full Review


Type: BB air revolver.

Manufacturer: UmarexUSA.

Model:Smith & Wesson 327 TRR8.

Materials: Mostly metal with some plastic construction.

Weight: 2.3 pounds.

Barrel: 6 inches, non-rifled.

Propulsion: 12 gram CO2.

Action: Revolver, single & double actions.

Ammunition Type: 4.5mm steel BB's.

Ammunition Capacity: 6 rounds.

FPS: 400fps.

Trigger Pull: The trigger pull on the Umarex Smith & Wesson 327 TRR8 is good in both single and double action, I wouldn't say it isn't supper light in either action but pretty decent overall. I found shooting in single action to be the most precise as the release point is instant. Shooting in double action was also fairly predictable.

Accuracy: The results I got shooting my 6 round group from a 20 foot out position where none other than impressive and I would have to say the 327 TRR8 shot the best group (just over a 1/2 inch) I have ever recorded using 4.5mm steel BB's. I'm not even sure if I have bettered these results using pellets from a rifled barreled pistol? This goes to show you how well an accurate BB gun can perform when shooting from a reasonable distance.

Build Quality: With the Umarex S&W 327 TRR8 Revolver being mostly metal, you would expect it to have a decent build quality and I am happy to say it does. Everything looked and fit well, the CO2 Revolver had good heft to it and I had absolutely no problems shooting this gun. My only real reservation is the plastic CO2 screw tab but so far with my other guns that have the same type of tabs, they are holding up well.

Realism: The Umarex Smith & Wesson 327 TRR8 is very realistic in terms of looking and operating as a revolver with it's brass shell casings you load juts like a real revolver, so yes it feels realistic and even looks a lot like a S&W 327 TRR8 to some degree. With that said, Umarex has taken some liberty on this one most likely because it is built off an existing airgun frame and to make it into a true 327 TRR8 replica would have required a complete redesign. I would have to say the Umarex S&W M&P R8 is actually a closer 327 TRR8 Replica than the gun reviewed in this video.

  • Plastic CO2 screw tab could cause problems down the road?
  • Only shoots BB's - why not make a pellet version with a rifled barrel?

What's not to like about this Umarex Smith & Wesson Revolver? It's built very well, it most certainly looks good, it has the best tested accuracy I have seen so far from a BB gun, it shot even higher velocities than claimed, it gets tons of shots from a single CO2, and it loads up just like a real steel revolver but at a fraction of the cost to shoot! If you want to customize yours you have plenty of options with two weaver mounts top and bottom and it comes in at a very reasonable price tag!
