Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol Field Test Review


I have already done a Preview Video where I show you around the Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol so check that video out for a closer look.

In this Field Test Shooting video I take out my Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol and put five shots through my Chronograph to see what the real word velocity performance will be, I also test the accuracy of the Smith & Wesson M&P40 by placing ten shots down range at a paper target setup 30 feet back using a semi rested shooting position(Pistol rested on a sandbag while standing in the back). I also include some slow motion video of the Umarex Smith & Wesson M&P40 CO2 Pistol blowback action close up for you to see how it cycles.

For my Feet Per Second portion testing I inserted a brand new CO2 cartridge along with 5.1 grain RWS nickel coated 4.5mm Steel BB's. The temperature outside was 15 degrees Celsius (59 Fahrenheit), so not overly warm or cold, On a warmer day I would expect a little higher fps for sure. Umarex claims a velocity of 310 fps from this pistol, As my Chronograph was misbehaving a little I was only able to get a three shot to record but was able to get a fairly realistic average of 299 which was pretty close to the claimed fps for the Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol.

Moving on to the Target Accuracy portion of my Field Test, all 10 shots landed within a 2 inch grouping, not bad for a full blowback BB pistol. I did notice the shots where a little low so some sight placement adjustments would be required depending on your shooting range since the sights on the Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol are non-adjustable for elevation, they are however adjustable for windage using the front sight to make adjustments. The blowback action is nice and heavy and the single action only trigger release is fairly light and kind of sneaks up on you a bit til you get used to it. You should be able to get around 4 magazines out of the Umarex Smith & Wesson M&P40 CO2 Blowback BB Pistol as long as you take some time in-between loading up your magazines to let both the magazine and gun warm up a bit from the cold CO2.

I have been waiting a while for this version of the Full Blowback Smith & Wesson M&P40 CO2 BB Pistol, and I am happy to say I am not disappointed in the least, it's a really great replica from Umarex and a must have BB pistol in my books!
