Thanks for the rep and I've had a little practice at the lead free range I work at. Right now we have some crappy 223 so as was suggested it was the ammo not the gun shoot what you want maybe some of the Hornaday steel cased stuff?
Thanks for the rep! If you decide to go with the Dawson sights you will like them. I currently have them on 3 of my pistols and they are holding up well in competition. Give them a call if you have any questions, they are good to work with.
