I am the range captain at our local range and have 1911s and a Glock in 9mm (as well as other calibres).
We get people who have never shot a gun before coming up to try shooting and I usually get them to shoot my GSG (German Sport Gun) 22LR 1911 replica, which they really like.
Our cops carry Glocks (in 40S&W) and the newbies are fascinated by the Glock usually, but the factory ammo or IPSC loads are a bit healthy for some of them.
I have lighter springs for my 9mm Colt, but it is the Glock they want to shoot. And I would like to work up some lighter loads.
Are there lighter spring available? I haven't spotted any, maybe I am looking in the wrong place.
