I've had my R9 for well over a year now, fired hundreds of rounds through it,with no malfuntions. I've carry it constantly 24/7 as a backup since I first shot it. Last week, while I was on vacation, I went to my sisters' house, for a few hours for dinner. I decided, since I was only going over to her house, I'd leave my R9 at home, and just carry my P228. I couldn't believe how much I missed that thing!!!!! I felt like I'd left my child behind in a busy shopping mall parking lot:o I guess I won't let that happen again
