what size pin?
 

The sword sight im looking at offers .10 .19 .29 What size should I get. I mostly hunt and I am looking into starting some 3d shoots. Thanks for any help

Sword pins look a lot smaller than what they say. I would go for the .029 pins. I have a sword sight setting on the desk here. It is .019 an they are too small for me. I went back to what has always worked for me.
