I have been following this forum for the last two weeks having purchased my Caracal C with quick sights about six weeks ago. I was going to see if Tooltech Gunsight, Inc. would be able to put in Trijicon sights as that is who Trijicon recommended. Then I read the post on the Waffen Werks Caracals and when I read about the potential collectors value (mine is one of those SN CL 615) I had second thoughts about having any drilling of the back sight done least I screw up collectability. I have now ordered some Bright Sight paint with the intention of brightening up the front sight dot and painting the back sight up in some manner to make it easier to see at the range. I am not sure what I should paint on the back sight to get best results so I am asking for some thoughts on this. I am new to this forum and I have read a lot of good information here which I appreciate. I live in the Madison, Wisconsin area.
