Blackhawk T Series Holster
The @BlackhawkTacticalUSA T Series holster line is a good option if you are looking for a holster with active retention. No doubt this is a better design than the older Serpa line of holsters because it uses your thumb to disengage the locking mechanism vs your trigger finger. I specifically purchased the T2C model for my @GlockIncSmyrna G19 to use in Run and Gun style competitions. I wanted to cut weight from my kit wherever I can and the T2C is half the weight (and less bulky) than my @TheSafarilandGroup 6390RDS. The Safariland is a great duty holster, but again, I was all about cutting weight and bulk. Overall the T Series holsters seem to be well made and secure. Plenty of options out there if you're in the market for a new holster with active retention.
