FPS: Claimed 300+ Getting the Umarex BB versions of the Glock 17 and Glock 19 has for sure been a bit easier since fps velocity is not a factor. So it was great that we where able to import at least some of these Umarex Glock 17 4th Gen GBB Airsoft Pistols into Canada. I hope we will be able to continue supplying the Glock Airsoft versions in our Canada Replica Airguns Store but I can not promise anything… So if you see some in stock then grab one while you still can!
