The TLR7 is my EDC light choice due to it's size/weight/power. I have one on my PX4CC and G19 G5 MOS. I have 3 holsters that are working excellent for the G19 with the TLR7. JMCK IWB3 Light Bearing, Black Rhino Concealment ACS AIWB and a Black Rhino Concealment FCS Paddle. All three have the optic cut as I have a Holo 507C mounted on the G19.
