I think you'll find that is a difficult question to answer. Holsters seem to be individual type things, and folks tend to have drawers full.
My suggestion would be to look around here to see what is popular. You'll also probably get some good suggestions and a couple questions, since we have some of the finest holster makers hanging out here.
Also, since you mentioned weight...... Don't forget about a proper belt, sometimes that can make all the difference in the world!
