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.
