    WHat does it mean if I have forward and backward motion of my cylinder in full lock up. I have several others and I do get that "welded to the gun feeling" however in my new 360 I can feel about a half mm wiggle forward and back
    1) what does it mean?
    2) how can I fix it?
    thanks forum I appreciate all your help

    Full lock up is where the trigger has been pulled and held back. Prying on the cylinder of revolver at any time is a quick way to make is loose. If the gun shoots well and doesn't spit lead between the cylinder gap then there's no problem to fix.

    .5mm is quite a bit and I suspect it is not that much, but some detectable movement is common and not a problem no matter what some experts say.

    Midway USA has a short video on Youtube about shimming out cylinder end play. A slight barely noticable end float is OK but if it truly is .5mm or more I'd be looking at shimming the cylinder if it were my gun. See if you can get the internal jaws of a set of calipers in the gap between the frame and cylinder and check for the difference between fully forward and fully back.

    Half a millimeter is .020". You would see the cylinder/barrel and cylinder/recoil shield gaps visibly changing. I seriously doubt it is that much. Try checking the gap with feeler gauges, selecting different thicknesses at both ends of the cylinder travel until you find the one that fits; the difference between the thinnest and thickest is your actual end play. I suspect it is more like .002". :)
