Please note this is for a Glock 19M, with a TLR-7A attached. If possible, I would prefer a closed end holster that may provide some retention without the light - no need for the holster to also accommodate a Glock 17. Also, please confirm the RDS cut will still retain a pistol without a mounted red dot? This is for plainclothes duty use and I anticipate my agency approving RDS use in the near future, would love to still use the same holster.
