For the past two years I've always carried with an IWB holster simply because it is so much easier to conceal. When I have spotted people carrying in public it's always been when their shirt rises up and shows some barrel/holster. I mostly wear an untucked oxford and with an IWB I feel really well concealed. I can draw well, and while I can't reholster with one hand: is this something a citizen really need to do? For a cop I can see why reholstering is critical, but for me I'm not sercuring anyone or patting people down.
Now I'm looking to take a "serious" CC course and from what I hear most instructors don't allow IWB holsters, is this correct?
If you think IWB are OK, what one would you rec for a glock 30? If you think I need to go to non IWB holster if I want to take a cobat course, what holster should I get for my glock in that case?
