GS on my CCO

[Trekinhipe]

Does anyone else here have a CCO with a loose fitting GS? It works as it's supposed to, but when shaking the pistol it rattles from a loose fit side to side. Like I said, it works, but is a pesky little 'mind bother'. I use it as my carry gun in a IWB holster and was concerned that the rattle would be a 'tattle-tale' to the gun being there, but wearing it under a shirt seems to keep it muffled. Anyone know if it can be tightened up? Maybe by bending the hammer spring a little? Or am I just being anal? Other than that, this is the best pistol I have ever owned!
