Glock 17 Gen 4 by Umarex

My take on the Umarex Glock Gen 4 Co2 4.5mm BB blowback pistol. Sorry for the Delay in upload. However I managed to get:my hands on a reel steel Glock 17 Gen 3 9mm for comparison! Thanks to Phil and Tracey at Leicestershire Airguns for loaning me this for test. Without their help I wouldn't be able to do these videos.
