I used to use a Federal ambi holster, but the retention straps were a little iffy. I have since gotten an Uncle Mike's ambi which holds the retention straps far more securely (it takes a tool to undo or adjust the velcro underneath the "Strap Traps"). Both have thumb breaks. It's the best of both worlds; the strap, with practice, is a negligible obstacle to drawing, yet it provides pretty solid retention.
I also have a holster for my .22 pistol when I'm using it as a snake gun (9mm HydraShoks is kinda overkill for that particular purpose
). It has a retention strap WITHOUT thumb break, and it makes me glad I have the thumb break for my 9mm.
A question for the crowd; which way do you position your thumb break? Do you have the snap on the inside of the holster so your thumb is closer to its grip position when opening the strap, or on the outside which, at least for me, is easier to break? I have mine on the outside because it's easier and thus faster, just curious how everyone else does it.
