This holster has proven to be great. It is very reasonable priced at optics planet for under $40, and is perfectly functional. The thumb break was extremely snug to start but after working it in, it now works great. It conceals my Glock 17 very well, especially for a full size. In just a T-shirt the gun is almost completely hidden. I'm not sure how well it would tuck under a shirt, as that would be quite a pain to keep tucked, but overall it is a great holster.
Pros: Price, concealability
Cons: It is a chunk of plastic
