Might be my favorite holster yet - Safariland 527 Pancake Holster - Plain Black, Right Hand 527-83-61

I waited on this forever because judging by the pictures it appears this would hardly hold your gun and you may experience your gun falling out! Well, there is GREAT retention on this thing for an open top. There is some sort of grabbing device in the suede that really gets a good hold on the trigger guard. I have a few Glocks and I like being able to use the same holster for multiple guns. I definitely recommend this for conceal carry, but for open carry in public I would prefer at LEAST a leather thumb break for retention. Great holster! BUY IT!
Pros: good retention for an open top holster
Cons: a bit pricey for a simple bare bones holster
