Need advise on a sight

[bigbob1]

I purchased a HI-VIZ sight for my Ruger P-90.  Went to put it on and the roll pin's are what I thought 1/16" so I got out the punch to take them out but they sure look SMALLER to me, almost like 3/64th's.  Ya, I can just drill out the pins with a 1/8" but then I have to hunt down roll pins to put back into the larger holes.  All the installation videos show ONE roll pin, I have TWO roll pins.  NEWCOMER needs alittle help  Thanks  Bob

Hi Viz company might have the answer?

I wouldn't try oversizing it unless absolutely necessary. Take your 1/16th punch chuck it up in your hand drill and cut it down to the matching diameter by spinning the punch onto a spinning grinder wheel. go easy and cool it in water so as to not over heat and soften the punch. first just grind down only about an 1/8th" of the tip and get the roll pin started to move out, then grind back more of your puch to get in deeper. Other wise you can bend a long skinny punch with starter hits where a short stub tip will get more force on the pin to start it out. You might be able to reuse the pins.
