Swartz safety on a Kimber. It is easy to remove the slide mounted components, which I have done on my 9mm Kimber M1911.
I have not taken off the part activated by the grip safety. Maybe someone knows an easy way to do this, and whether it will affect function. The thing is a total bother when assembling the pistol after cleaning. You can't use a normal grip frame hold, without part 21 sticking up through the frame, and it prevents assembly of the slide to the frame. I hate it.
I also hate the series 80 safety.
I have had the series 80 firing pin plunger drop down, as the slide was cycling, and block the slide from going into battery. What a terrible design for a self defense weapon. The pistol jams, normal practice is a rack and tap, which is not going to clear this malfunction. You have to take time out, to turn the pistol around and over, puzzle out the not obvious malfunction, see the little plunger sticking down, use a couple of hands to clear the round, drop the magazine, push the firing pin in, push the plunger in, and by then, you are dead.
This is a combat pistol, follows the original Browning design. Called the series 70 even though it dates back to 1910. You lowered the hammer with a round in the chamber. You thumb cocked it when you wanted to shoot. Which is why the grip safety is smaller than a beavertail. It is hard to thumb cock a M1911 with a beavertail. The safety was only there to make the pistol safe with one hand. You learned to lower the hammer with one hand blocking the hammer, and the other pulling the trigger, because if you lowered the hammer enough times with the shooting hand only, the hammer slipped out from under your thumb and you made a hole in the floor. Sometimes made a hole in a person. I found in a 1917 Arms and the Man, a Camp Perry competitor lowered the hammer on his M1911, in his tent, and shot a Military Officer 200 yards away, when the hammer slipped. Oppsie! Other than that, it was pretty straightforward to operate.
