They are very comfortable. It was hard to wrap my thumb around the butt at the start of the draw, so you start with your fingers then wrap the thumb. The poster "bigtaco" asked me about this, and I decided that was a hazard. So I cut off the top piece of leather that extends up from Kydex. That decreases the comfortability to a pretty minor degree, but makes it a lot easier to draw in difficult situations.
I realize the idea of cutting a new holster will be objectionable to many. I think that with the top piece removed it is a good holster for me. Some may be able to wrap their thumbs with the top piece on.
I still think the advantages are good value (low cost for what you get), and comfort. I have no need for any other IWB holster.
The guy who does them (Craig) was a good guy to deal with. I would buy with confidence from him again.
Thanks to all who replied, I appreciate the input. I have used Don hume open top IWB leathers for the past 6 years since I graduated from synth/nylon for off duty. I am going to p/u my first M40 and seem to have to upgrade to custom gear for the new toy. The Crossbreed stuff seems to have covered all of the cost,concealment,quality issues. Now I just have to be patient and not try to stuff new gun into another holster just to get it some airtime. :wink:
