HI folks, a newbie here with a question. Put about 350 rounds down range with absolutely no problems. Disassembled the weapon for a good cleaning and for the 1st time it wasn't to bad. Reassembled and racked the slide and all appears well. I did notice that there is a rocking motion in the slide from side to side. Was wandering if that is normal or if I messed up the assembly somehow. Any replies would be much appreciated.
