Ray, if you use a belt holster (IWB or OWB) your gun is going to be seen when you take your jacket off. No way to get around that in your situation, unless you wear a long vest that covers your belt. I don't see how you're going to get by with anything other than your ankle holster that you're now using. I carry my Shield every day (OWB) and it works great for me, BUT....I always wear my shirts outside so that the holster is covered. Or a sweatshirt. Again, in your case your suit jacket will hide your OWB or IWB holster until your remove your jacket. Try to stick with your ankle holster IMO. Or maybe consider the S&W M&P Body Guard.
