dao,
You might want to contact RUSTY22 to see if he is still offering his BMT (Buckmark Maintenance Tool): http://rusty22.com/Projects-BMT.htm
It's really handy to have. It makes removing and installing the slide much easier. The top rib screws can work loose (you'll know because it will begin to misfeed) so the hex bit on the tool is useful to have with you....besides it also helps loading magazines.
Here are two good BM sites:
