I highly recommend the Blade Tech Nano IWB holster. It's reasonably priced, comfy, and you can wear it pretty much at any position inside the waistband.

I think holsters for conceal carry are different from person to person and especially with the type of body different people have. I have learned through the holsters I use that I have to just go to the store and try each one for comfort. There are a lot of great brands out there, but I would first identify the type of holster that is comfortable for you i.e IWB (Inside waist band) or OWB (Outside waist) paddle holster which is outside the waist, shoulder holster and many more. Try searching Youtube for concealed carry holsters to see different types that way and then definitely visit the store as I know a lot of gun stores would be happy to help you try different types.

I have been using the Undertech undercover shirt and t shirt for my VP9, and have been very happy with them. I do find it requires a second layer such as a blazer , or looser shirt to conceal to a greater degree, but for comfort and basic EDC, I am very satisfied. Good luck!

.You mat want to try a HK VP9 IWB Holster.The Infidel Ultra Max Holster would be a good
starting point.
