Sousana brings up a good point, disabling a factory safety can come back to haunt you in the future.
Is the gun for Self-Defense/Carry, or for just target/range use?
If it is for self-defense only, your liabilities increase 500% over just a range use gun.
If you were ever to have to use it in self-defense whether it is a range gun or a primary defensive weapon, you will be hung out to dry if you have to go to court and have to explain why you disabled the safety. And it will be extremely hard if it's your Carry weapon.
Hope this helps.
Just my 2¢ worth!
But, if you must get rid of those parts, i'll take them off of your hands. That way you don't have to deal with all those EPA rules about throwing that stuff away.
