Novak's one-piece backstrap
 

Anyone seen these? Replaces the mainspring housing and grip safety all in one shot. I really like it! :)

It's one less moving part and keeps dirt and grime from getting inside the gun. Only concern would be from evil litigators (removing a safety - playing up the "no matter how unneeded or redundant it may be" angle).

Evil litigators? Isn't that redundant, like saying "hungry shark" or "prissy FS"? :p
