Airsoft Zeel goes over the WE Glock 17 Gen 3 if it still worth getting this variant when there are the Gen 4 and Gen 5s already in the market. This a good replica of the Glock 17, a popular pistol known for its durable polymer frame and use by military and law enforcement worldwide. It even has a rail for adding accessories like lasers or lights. While upgrades are available, the gun is so well-made you might not need them.
