Umarex made some compromises with the blowback action to increase the muzzle velocity without affecting shot count. The slide doesn't go back as far as far as some of the KWC blowback pistols, like the tanfoglio witness 1911 and the Swiss Arms p92, but those pistols shoot steel BB's around 320 fps while this M45 CQBP 1911 actually does shoot as high as the manufacturers rating of 400 fps! The open sights are excellent three white dot sights that make target acquisition much quicker than without the white dots. All in all, this is a very realistic looking Co2 single action semi-auto pistol with snappy blowback.
