Certainly not a bad rig. It does solely rely on your belt pressure for any retention and reholstering one handed isn't gonna happen.
All that being said and these things aren't a concern it should be fine if it works for you.
I absolutely hate thumb breaks but with this kind of holster it might not be a bad option.
I used to carry cross draw all the time when I worked in a tool warehouse where I wasn't supposed to be carrying as usual. It allowed me to see if I was printing and seemed to be more out of the way and not getting banged around. I even got patted down a few times and because I had it further back than normal like 7 oclock position they missed it.
Funny thing was we once in awhile had a shoplifter or angry customer. People weren't allowed in the warehouse but there was a little counter sales area and they could easily just wander into the warehouse, no partition. But whenever that happened they would always page over the intercom for me to come??? I was probably the littlest guy in the place, I even asked why you calling me?
Ask me now questions, I'll tell you no lies I guess.
