Do you guys find this holster user friendly and easy to conceal? I'm am fairly small framed guy and want to carry a medium sized automatic. I like to carry around 3:30 or 4:00. There are few options for this particular gun, an FN P9. Id like it to to be easily removable for driving and locking up while at work, I'm not sure how easy those snaps are to undue. Let me know your thoughts.
