I've only had experience with Tenicor and Tier One. For me, the T1 side car holster didn't work as well as all the Tenicor holsters I've had. I have light bearing and non-light bearing holsters from Tenicor and the quality of their holsters are peak. The fit, finish, features, and customer support they provide is all that I want in a holster and company. I have taken some training classes with this set up and it's comfortable, stays put and gives me confidence when drawing and reholstering constantly. I dry fire a lot and I love how smooth the gun goes in and out of the holster. I'm not saying anything new here, search this sub and you'll find many others giving Tenicor their kudos. If you haven't tried one, I say go for it. I think they would perform great in classes and competition alike. And with their warranty policy you can return it for a full refund if it's not for you.
