4 Pack 31.8MM Aluminium Alloy Cycling Bike Bicycle Quick Release Seatpost Clamp, 4 Colors

Yeah, that is what I did as well. It was more than fine. I'm not saying a GX isn't great or well made- far from it, but if someone is looking for a new holster and really wanted the locking feature. Cheap - Comptac or Bladetech and buy a screw in bike wheel release Mid-tier - Buy a RHT holster (or other kydex) and a Grainger or McMaster-Carr clamp And then after wards if you feel like waiting 20+ weeks, GX.
