Amazing Glock 19 Airgun Replica

Checkout the Umarex BB Airgun of the Glock 19 (3rd Gen) replica. It’s insane. Pictured is the air gun and my actual Glock 19. My son had the airgun in his car glove box. My wife found it and about freaked out. I told him there was no way he could carry that in his car - even if was only an air gun.

With the convenience of a still photo, it doesn’t take long to see the differences but at first glance, they are incredibly similar.

Which one is the real Glock 19?
