Springfield XDs 3.3 Cloak Tuck 3.0 IWB Holster (Inside the Waistband)

They do help in not 'printing'. More or less hide the fact that your concealed better. You might need to get new belts for your pants as its inside the waistband. However I think this is going to boil down to personal preference. As I have big hands I like full size grip of my CZ 75 SP-01 Tactical and small of back holster.

I have the cloak tuck 3.0 myself. I carry my glock 22 Gen 4 in it daily. By far the best concealed holster I've owned. I'm not a hefty guy so full size carry is tough in the warm weather but this holster is a definite win all around. Suggested carry withthe 3.0 is the 3 o'clock and about the 430 position. Just depends on your comfort and access.

Don't leave out the Alien series holsters. I've had both and like the Alien.... I also carry a S&W M&P Shield (9mm) in a Galco ankle holster.
