This is Glock 19M Gen 5 with Acro P-2 sight with a TLR-7A Streamlight. I believe the light has a 1913-1 base plate but not absolutely sure. I'm going to email you a photo of the light. Also, I was emailing with your customer service team, and they said due to the height of the sight, plus the light, the holster must be straight, not canted. To the extent you can (if possible) please try and cant the holster. But if no cant is possible, no worries. Straight holster will do. Thanks for your work.
