How to change speed of Siminov's weapons?

I’ve tried setting the speed on the base of all the weapons and on the weapons themselves to the speed I want. In my DarkRP the Walk Speed is 160 and Run is 240. When you pickup a Siminov weapon you start running real fast and the walking is like 240 and Run is like 500. So I need some help on how to limit the speed on Siminov’s because the Speed Bar where you can adjust the speeds do not work.

Thank You!
