Robust and handy - but only vertically

My 'batch' came years ago with this holster, and it has always served me well, even if I wore it often wrong - it is faster and more convenient reach, and the pushbutton considered it reliable. Only when I started to wear narrower belt, I have looped horizontally. The result was that after a few weeks of the rubber was so worn out that I thought a seam would be worked out - but they are in order ...
I wear it again vertically and look around for a new holster around - but this is no longer an option;
1) due to the exorbitant price,
2) because of the vulnerability rubber sidewalls :(
