No danger of the safety not working as if you over shim it you wont be able to get the bolt in or out. so it gives you an easy indicator as to how much shim your trigger needs.
The return spring mod is an addon to the trigger spring which gets the majority of the lightening done and again is very easy to do. The trigger spring alone got me down to about 5 lbs and the sear return srping netted anoth 1 & 1/4 or so.
Any sear surface polishing or mods that will effect safety, then yeah I absolutely agree, take it to a gunsmith. But both the above mods are super easy to do and pretty hard to get wrong
