^^^^^^^ Not all Gen Glock are the same and additional things can be done to help make a Glock fit better.
I liked Gen 1's but hate Gen 2's. Gen 3's fit better but the trigger guard dug into my index finger while shooting. The gun frame being made of polymer can be sanded and molded to fit almost anyone's hand. There are also nice slip on rubber grips that imo transform the gun into a comfortable easy to shoot weapon.
