Trigger Pull: The trigger pull on the Umarex Smith & Wesson M&P R8 is not too bad but has a stickiness to it right at the beginning as the cylinder rotates and pushes the metal spring "feed ramp" in and out. Shooting this revolver pre-cocked in single action mode is a bit smoother but also has some resistance right at the beginning. Overall I would say it has a medium pull to it. UPDATE: When actually shooting this gun, the trigger felt very respectable and I was able to get excellent accuracy result shooting in both single and double action.
Accuracy: Very good! I got 6 out of 8 shots inside my 1.5 inch bull’s-eye and only two shots went outside a bit. these results where done shooting from 20 feet out in a semi-rested position. I also shot freehand in double action shooting quickly and also got a fairly well placed grouping. When it came to FPS performance the Umarex S&W M&P R8 was a bit disappointing (336 fps average 8 shots) but on the plus side it got well over 150 shots per CO2 and was extremely quiet to shoot.
Build Quality: This is an almost all external polymer air pistol with some metal components on the inside like the inner barrel, hammer and some other internal framing components. The fit and finish is very good on the S&W M&P R8 and the plastic seems rigid and does not have much flex to it. Overall the R8 has decent weight but I felt another half-pound would have helped this gun out.
Realism: The Umarex S&W M&P R8 is a licensed replica of the actual Smith & Wesson M&P R8 revolver. It is a very close looking copy in almost every way. There is a lot of attention to detail that helps make this gun very believable like the Smith and Wesson markings throughout the airgun and full size swing out cylinder!
Comments: The Umarex Smith & Wesson M&P R8 BB CO2 Revolver based on my first impressions in this table top review portion is a rather nice low cost CO2 revolver. Other than its low cost, it has a lot going for it like the extensive Smith & Wesson trademarks and the full size swing out 8 round cylinders, just like its hard hitting 357 big brother. The S&W M&P R8 also has an adjustable rear sight and full single and double action trigger for fast paced shooting or slowed down precision. I also really like the well hidden CO2 tab and larger diameter barrel opening that add to the realism of this Air pistol. Yes it shoots BB's only, and yes it is mostly plastic but I think once you start shooting this gun you will quickly forget these two minor shortcomings and remember how little all this enjoyment cost you!
