I have had the 20, 21, 29 and 40 and use the DeSantis Speed Scabbard for strong side carry. It can be worn canted or straight drop. I have not tried the straight drop crossdraw however.

EPS make one I have always wanted to try...it allows SS and CD...

Just bought one of the trigger guard covers that fit all Glocks from Lone Wolf... Usually carry crossdraw with no holster with the gun tucked in behind the left hip butt forward. Tried it with the G19 the other day and really like it...

Got rid of the 20, 21 and 29 as I just didn't like the grip or recoil... The 40 was kept as it is comfortable to shoot and isn't carried on body but kept in a pouch seatbelted to under the console...
