i have a SIG 229R ...and a brand spankin' new holster. i just received it today. it's safariland 5187 model. i have some retention screws on it, however when i put my weapon in it i just tighten it close to "all the way" so it could "stretch" out. any suggestions? i want to be able to USE my holster and not have to fight it when trying to unholster/reholster. thanks all.
