Concealment has a lot of advantages. If the bad guy comes in the store and knows that no one is armed (say in Illinois for example) then he isn't worried about people shooting back. If he comes in and knows who is carrying (open), then he knows who to shoot first.
But, if both open and concealed carry are allowed, the bad guy does NOT know who is carrying, even if someone is open carry. Because someone else may be concealed. And he knows for sure that someone is armed. Most criminals aren't looking for a shootout. They're looking for an easy pay day. Chances are they will go elsewhere looking for that pay day.
I'd say having both open and concealed options available definitely affects my carry style. It gives me more options and some of them are a lot more comfortable and convenient.
I find open carry to be considerably more comfortable. Until I can find a concealed holster that works for me, I will carry open.
I tried fanny pack, but the weight hanging out front was messing up my lower back. I have an Old Fashioned Holster (similar to Crossbreed Supertuck) that is OK standing up, but sitting down can be very uncomfortable unless it's in just the right position. Plus it's going to take me a while to switch over my clothing to pants about 2 sizes over my normal. I have a belly band on order that I may try wearing around the belt line at 4 o'clock. The search continues...
