+1 to all the above and my only caveat about removing the mag. disconnect has been that if you live in a prosecutorially hostile state like mine, you might err on the side of "Absolutely Unaltered Factory Sold and Approved Firearm" in case you ever have to use it in the worst way. I do not know if it has ever happened, but I can very easily imagine as plausible an overzealous prosecutor using your modded gun against you ("This GUN NUT removes the safety features! Like RAMBO!") in court after you've had to use it to save your life or someone else's. Here in MA they've been known to keep off-duty police officers in prosecutorial limbo for a year after they used their licensed weapon to turn the lights out on a knife-wielding maniac who was about to murder a physician in a hospital. He shot the perp., the perp died, and then he spent a year in prosecutorial limbo before the District Attorney finally closed the case. And that was with an unmodded gun in a crystal clear Use of Deadly Force scenario.
So keep in mind where you are if you decide to do it and weigh that against your use of the gun and whether you think it's worth it. Over and out.
