guys, I bought a used xds from a pawnshop. It was in great shape other than it was like someone poured a gallon of syrup in it. I broke it down all the way. I got it all cleaned up and put back together. My grip safety does not work now. It fires pressed or not. I know its not assembled...

I saw one with the shield optic installed and was very impressed. I never shot a pistol with an optic, but it was quick to get on target. Do any of you have this gun, what are your thoughts? I see where the optic is not battle ready, but seems good for CCW.
