If I'm in a hurry and don't want to bother with dressing for concealed carry, I grab this little trigger guard holster and put it on a slip the pistol down my right side. I can hardly feel that the pistol is there because there isn't this bulky holster protecting it. I use it on two of my Glock pistols quite frequently and the size isn't even listed! After doing some testing I found it works on Poly 80's that a friend has and the one I have as well as the Glock 29,30, 20 and 21. Perfectly...So if I was Bastion I'd add those models to the list.
