Bob--Thanks for the input, I checked it out on Ebay, and the tool looks like it would work fine. I guess my only concern in whether or not any sight pusher will be able to force my sight the last 1/16th of an inch or so that it needs to go. Do they really have that much more force than when I use a hammer and punch? How is your tool working out. I thought I saw a review on one of these tools (I thought at first it was this one at first) that it simply stripped the threads and didn't function well at all.....hopefully you had better luck with yours.
