I'm heading out to the rifle range to put some rounds thru my new GP-100. 
I installed the picatinny rail a couple of days ago and I just received the pic rail mount. Put a little blue lock-tite on everything and it should be good to go. This is the Holosun 407c and it has a green dot, which my eye seems to pick up quicker....especially in daylight. 
I'm excited to see how well it shoots at longer distances, even though I'm sighting it in at 25 yards. I don't expect to take shots at varmints, past 40 yards, but I'm going to see how well it shoots.
