I've been searching for an auto retention holster for my TS forever. Dropping a gun is always in the back of my mind at a 3 gun event. I tried to convince about 5 different companies to make me something custom (for well over $100) and they were either to busy to try or just flat out didnt want to. Finally stumbled upon the Safariland 578 GLS Pro Fit. I originally bought it for a 2011 I'm having built but the box said it would fit a CZ75. Sure enough, works like a charm on my 75SA, 97B, Czechmate, and TS . It will not, however, work with the CZC TS extended safety if it's engaged. You can either run it as is, and the gun will be slightly canted outward making for a tighter draw, or cut out a small relief for the standard safety, and it's buttery smooth. I have it mounted on an Invictus Practical holster hangar and I love it. Paid only $30 off ebay as well. Just make sure you get the long version.
I used a 5.11 thumb drive holster for my M&P and I thought that was pretty good. The down side to that is you have to keep downward thumb pressure while lifting the gun upward. You really had to concentrate to keep the gun from locking in on the draw. This grip lock system is much better IMO. The spring is weaker so there is very little resistance to depress the lock and it's right there when you go to grab the pistol. Nothing in my draw changed vs a normal Blade-Tech.
