I just had my local gunstore mount a new set of meprolights on my new G27. When I showed up for pickup the front sight post was slightly "cockeyed". The clerk quickly took it back and adjusted it and now it looks perfect. I was just wondering if this happens alot and if this is something I have to worry about happening after a range session. He informed me he'd used loctite on the sights and it shouldnt be an issue, but would'nt his readjustment have broken the loctite's hold? Also, how long should I wait after the sights were mounted to actually shoot. Any information would be appreciated.
