I had been hearing good thing about Raven online but never through to switch because my Blade-Tech worked fine.
After a week I can say the Raven works better.
The Blade-Tech was my first holster and it has proven to be very durable. The kydex on the Raven is significantly thinner. This is great for concealment.... for long term durability I don't know but I have no doubt after talking to the guys at the 1500 that they stand behind their product.
I had mine made up for my G19 at the 1500. I believe this model comes standard with the plastic pieces you see with a blue zip tie through them in the pic. I'm used to the "pull the dots" so I asked them to set me up with those.
The Raven is a better design. The holster is wider but conforms to the body much better. The pull the dot loops are in a better position because they are placed on either side of the gun so you aren't wasting valuable space. I also find that this holster is more forgiving for some reason. I can get the gun in and out a lot easier.
Overall I'm very impressed and the guys who own the company seem like good people who really stand behind their product.
