I feel your pain. One firearms training coordinator at my former agency decided to purchase only Safariland holsters that would fit our 226's with the TLR-1/Surefire 300 lights. (I don't believe the 7A was available at the time.) This was regardless of whether the officer had a light or even had a legacy 226 without a rail.
The next FTC mandated that all officers mount lights on their weapons. Of course, the newly issued FNS-9 was unreliable with a WML attached until FN replaced the barrels so some pistols were carried without lights attached.
