looking for glock 19 iwb holster with the following criteria:

Looking for a glock 19 iwb holster that is

Leather
Secures with loops, preferably fixed loops if possible
Thin and comfortable
For carry in the 3 O'clock position, possibly with a slight forward cant

I already have a gould and goodrich metal clip iwb holster, which is ok but tends to move around when seated. Anyway all feedback is appreciated. Thanks.

The Alessi (Burns Custom) GWH had a fixed loop. http://www.burnscustom.com/holsters.php

I don't see it available from Alessi though. You may need to ask. http://www.alessigunholsters.com

Here is a review from the holster's namesake Jason Burton http://forums.1911forum.com/showthread.php?t=265817&highlight=inside+burton+special

Del Fatti makes the ISP with a sewn loop http://www.delfatti.com/2011%20ISP.html

Some options.

It doesn't have the belt loops, but I own a few of the Alessi Talon and Talon plus holsters for Glocks and 1911's. The Talon clip is very aggressive and secure, gripping the pants underneath the belt, so even the clip is fairly hidden. I highly recommend the Talon Plus. They also have a fwd rake.

edit: I just looked at their website, the PCH and Hideout have belt loops

One slightly different option is the Nate Squared holster...They're leather with either an elastic band or molded plastic piece to keep hold the gun. They don't have a loop, but they do have a very nice clip. It's thin, strong, and metal. The suede backing also keeps it from moving when you're sitting/standing/moving/whatever. You can also set the cant that you like.

I carry my 19 IWB every day with the Professional model.
