Do any of you Glock 20 or 21 owners have any ideas on a concealed holster that works while a TLR-1 or TLR-1S is attached? I prefer IWB. The best option I have found is the Raven Phantom Light Compatible Holsters. I just don't want to wait 4 months for it to be made. Thanks in advance for any help you can provide in this matter!
