if it really bothers you, you can remove it. 70 series colts don't have it and neither do most custom 1911's. (i know someone is going to come along and say that removing it is bad if you have to shoot someone, liability, wah wah)
either way, to remove it:
- strip the gun as normal
- strip the slide (remove firing pin/spring, and extractor and while you are in there give it a good cleaning)
- drift the rear sight out of it's dove tail (IIRC, my kimber was left to right to remove, right to left to install)
- the top portion of the swartz safety will fall out (it's a [ shaped collar and a spring)
- reassemble the slide
- strip the frame down (remove the MSH, and all the internals)
- when you remove the sear, there will be a small b-shaped piece to the right of it which is the bottom portion of the swartz safety (this is the piece that is actuated by the grip safety, goes through the frame, and pushes the FP collar up and out of the way, grind off the finger that goes through the frame
- reassemble the frame
- reassemble the gun
it took longer for me to type out the instructions than it does to do the actual removal...
