I did some shooting last night, nothing different or strange. When I was walking up to the garage I felt something "fall" inside of my pant leg (I carry IWB). I didn't think anything of it. This morning I went into the garage to clean up the Glock and lube it up. I removed the mag, pointed my muzzle into my 5 gallon bucket of sand (yes, I have one of those) and pulled the slide back. I dropped the chambered round and then let the slide fall back. I pulled the trigger so I could lift up on the slide retainer bar, but before I could do anything the slide dropped off the frame and onto the bench! When I looked at the frame I found that the slide retaining bar was GONE! A bunch of little parts fell out of the gun (I don't have a diagram or a photo will all of the correct names of the parts). I can't figure out what happened. I remembered the feeling of something going down my leg and i thought it might be a part of the pistol. I walked over to where I was walking when I felt it and I did find a small piece. I can't find the slide retaining bar and I have idea what else I am missing. So is Glock going to fix this for me? How long does Glock take to fix these problems? Is this a common occurance with Glocks? I would like to know as I trust my families life to Glock. Thanks.
