What can you guys tell me about the TruGlo Rite-Site XS? Are the pins interchangeable to a .029 pin instead of the .019? How is the longevity / durability of the sight? How long can I expect the batteries to last in the light? What information can you guys give me? I know it's on the low end of the price scale. I do like the light though. That is impressive to me for some reason. Sent from my iPhone using Tapatalk
