Fairly new to concealed carry. Been carrying in a fanny pack. Just got an IWB holster (Old Fashioned Holsters) which is tuckable. I've tried tucking the shirt in. That act alone takes some practice. I've tried some dry fire draws and that's where my problem is arising. My normal attire is business casual: slacks, button down shirt tucked in, but normally no sport coat to cover. When I tuck in the shirt in a way that actually looks normal, I find it extremely difficult to actually pull the shirt out of the way at the start of a draw. Two or three yanks are needed to get the shirt out. What am I doing wrong? Tucking in too much? Is there some special way to fold the part that's tucked in? Are there any videos on line that cover this?
