Ok I think the general consensus is to run a G21 holster for my Glock.
Thanks for the tip Calvin, I will be picking up one of those up ASAP

Since we are all on the topic, I also have a TM MEU that I bought from Calvin, would the Colt Goverment 1911 holster for the MEU? If it will fit then I will be picking up both holsters from LA Police Gear to lump the shipping costs.
Cheers
Phil
