I have the Hogg-it Hunter, 7 pin. They make great sights. I dont think you will ever have any problems with it.
Not sure if you have seen it yet, but the hogg-wrap will make your pins a lot brighter. It bolts on the front of your sight, and adds a lot of extra fiber optics to gather up the light.
Ive never needed it, but some really like it. I think its about an extra $80.00
