The safety in this pistol can be removed during detail cleaning and just not put back in. Pistol functions perfectly without it. There will be little holes in the frame where it was, but fillers are available.

If you have a firearm with a safety you must put it on FIRE every time, even if you never, ever safe it. Mister Murphy will ensure it's on SAFE during moments of crisis so don't ignore it. With the M&P the best way to avoid this is to just not have the unnecessary safety in the first place.
