Crosman 2250 Security Screws in Pistol Grip ?

[kenj]

Just bought a crosman 2250 thought I would smooth the trigger but it has anti tamper screws?.in the handle.
Cannot think why the whole gun can come apart by the looks of it. Tried cutting a slot for the screw driver
With a Dremil no joy anyone any ideas tried to drill but did not want to melt the plastic.

On thinking about these screws they are probably that way to stop folk taken the stock off and having handles then 8 +_ lbs will be illegal pistol?
