Are there aftermarket recoil springs for the P99?

I think I need a lighter spring for practice because the gun wont cycle when I am using lead reloads bought from the firing range.

The gun works perfectly though when using factory loads.

Will your range not allow anything other than their lead reloads?

If not, the cheaper and easier alternative would be to just use factory loads from now on. Since you encounter no problems with factory loads in your weapon, the problem is the ammo not the firearm. Switch ammo
