Guys,

Just a thought. I have a DeSantis Nemesis holster made for a J Frame but also works for my Bond Arms derringer. If you're not familiar, the exterior has this polymer sticky material that binds to your pocket. It really does work well. This model has a removable outer flap that aids in printing through your trousers.
I haven't researched other models but maybe one will work for you. This holster is just the ticket IMO for front pocket carry.
