So I have a lot of friends who think Glocks are too "loose" or "sloppy" for their taste. I try to explain to them that it's that looser tolerance that keeps these machines eating any ammo you throw at them. BUT.... i just bought a new Gen 3 G29 and the play in the slide seems to be excessive. With the mag out of the gun, the slide will rock back and forth from side to side on the frame. Shaking the gun from side to side makes it sound like a pile of crud. This is my 3rd glock now and I have never run into this before. Is there anything i can do to remove some of the play or is it a non issue? Should I send it back to glock?
