Umarex Colt M45 CQBP Blowback CO2 BB Pistol Field Test Review

Make sure to checkout my Table Top Video and Written Review for the Umarex Colt M45 CQBP Blowback CO2 BB Pistol where I show you around this Umarex Blowback BB pistol and go over its features and specifications.

This Field Test Shooting Video Review focuses on the performance results of the Umarex Colt M45 CQBP Blowback CO2 BB Pistol. I put it through its paces to see what kind of velocity it can achieve as compared to the 400 fps Umarex claims on the packaging. I also perform my standard 10 shot accuracy test from 30 feet back to see how this action pistol groups on paper.

My first portion of the test, the feet per second velocity test I performed using my Chronograph shooting five 5.1 grain standard zinc coated steel BB's with a brand new CO2. The fps for the Umarex Colt M45 CQBP Blowback CO2 BB Pistol ranged a little from 334 to 358 fps with an average 5 shot reading of 348 feet per second. Keep in mind the temperature was not exactly warm on this day, just a little over 10 Degrees Celsius so I was not anticipating top claimed fps readings so hitting about 50 fps under claimed may be a bout right, I know for sure on a hot summer day I can expect better results.


Next up was the accuracy or shooting portion of this field test shooting review, I performed my standard 30 foot back paper target test using a semi rested stance standing in the back with a sandbag up front to rest my hands on for stability. This position is nice and stable but not perfect so there is always some human factor to take into account. Removing one flyer that was rather high, I was able to get a 3.5 inch grouping from my Umarex Colt M45 CQBP Blowback CO2 BB Pistol which is what I would consider about average for a blowback BB shooter, not the best but far from the worst I have shot. I am pretty sure I could do a bit better once I got used to the trigger as it does have a lot more take-up than I am use to with a 1911 and the release is a bit firmer.

A couple of observation when shooting the Umarex Colt M45 CQBP Blowback CO2 BB Pistol. I found the trigger to be noticeably longer and heavier than a standard 1911 but at least it is single action and I would say usable once taking a little time to get accustomed to it. The break point is rather deep and the release can catch you off guard but again putting some rounds through the Umarex Colt M45 CQBP Blowback CO2 BB Pistol will work much of this out. The Blowback action is not overly heavy but certainly enough to give that recoil effect. I would also suggest only placing 15 rounds in the magazine as the load of the follower spring for a full magazine can play a little havoc with the trigger.

All in all this is a nice 1911 Blowback BB pistol option especially if you are looking for a 1991 that shoots a little harder and gets more shot per CO2 than the KWC/Cybergun 1911's since you can expect fps performance in the mid to high 300's and at least an extra magazine worth of shots per CO2 from the Umarex Colt M45 CQBP Blowback CO2 BB Pistol

Trigger Pull: The trigger pull on the Umarex Colt M45 CQBP Blowback CO2 BB Pistol is like the original 1911 semi auto pistol a single action only trigger. That said the Colt M45 CQBP SAO trigger is notably longer than a true 1911 trigger would be but still pretty decent overall. There is a fair bit of take up but once you get to the release point the trigger weight is about a medium pull and should allow for pretty fast action shooting with not too much finger fatigue.

Accuracy: I have not shot this "version" of the Umarex Colt M45 CQBP Blowback CO2 BB Pistol but I have high expectations that it will get much better fps and CO2 efficiency than the similar looking KWC versions out there. 400 fps for a blowback is pretty good and if it can get about 5-6 magazines worth of shots that would be close to double of what a KWC 1911 blowback gets! In terms of accuracy only time will tell when the weather perk sup here a bit and I can get outside and make some shooting videos...

Build Quality: I am very impressed with the build quality for the Umarex Colt M45 CQBP Blowback CO2 BB Pistol. In many ways it may even be better than the KWC 1911's as it seems to have a much more durable finish and the mechanical parts fit together very snug with virtually no slide wiggle at all. This little rather inexpensive 1911 blowback BB pistol should last you a long time and perform well doing it.

Realism: Up to now I have been almost preferring the Umarex Colt M45 CQBP Blowback CO2 BB Pistol over the KWC Blowback 1911 series but when it comes to realism the tables turn a little bit in favor of the KWC 1911 version. On first look it is hard to tell them both apart so yes they both look and feel very much like real steel 1911 pistols. Once you get into some more of the mechanical aspects the Umarex Colt M45 CQBP Blowback CO2 BB Pistol does make some compromises choosing to take away a little bit of the realism in favor of increasing performance. These area are the range of motion of the blowback action. On the Umarex Colt M45 CQBP Blowback CO2 BB Pistol the slide range is a bit shorter which will save on CO2 usage and the magazine is a stick mag setup which again allows for a more enclosed system again taking advantage of all the CO2 being used. Most of the mechanical parts work as you would expect them to on a real 1911 with the exception of the grip safety. The barrel is even nicely recessed ti make the barrel opening look like a real 45 auto. Lastly the trigger even though it is a true SAO trigger does extend out from the gun a lot more than a true 1911 trigger would.

I can never seem to get enough of the Blowback 1911 BB pistols when I have the opportunity to review them. Most of them have been just different reskinned, rebranded and redistributed version of the original KWC 1911 so it was kind of nice to get the Umarex Colt M45 CQBP Blowback CO2 BB Pistol since it offers that 1911 look with blowback action and from the looks of things it should have improved performance in the shooting department. If you have been after a Blowback 1911 BB pistol but wanted one with some more power and that you can get a decent amount of shots out of a single CO2 then the Umarex Colt M45 CQBP Blowback CO2 BB Pistol may be just what you are looking for.
