I thought Kydex would be the way to go with my new to me Glock but wasn't quite ready for Kydex only, I've had a few all Kydex and polymer holsters from BladeTech and others and never really cared for them all that much.
I wanted OWB as the G21SF is mainly going to be for IDPA and possible winter carry if I decide to carry it. I went with Comptac as they have one of the quickest turnaround times in the holster industry, I had my gear in 10 days, I ordered on the 14th and it all came in today.
One Minotaur Gladiator Holster, two single mag carriers with Tek-Lok and of course the Smarties (not pictured, SpeedLoader ate them). Seems like some well made stuff, but the mag carriers are definitely on the thick side, I think good leather double mag carrier is in my future to have a less "bumpy" profile on my belt. One of the things I like about this gear is that I can adjust it for different belt sizes. I tend to use a 1.75" belt for competition as it is a little stiffer and handles the additional weight of AR mags quite nicely.
The rig seems very well made, I should have a better update on it tomorrow as I'll be running this set up in the local IDPA match.
Here's the pics.
