I'm issued a G17 with Streamlight TLR-1. I've moved out of patrol (Detective)...as such, was issued the 6378 w/ Paddle attachment. The Paddle is VERY comfortable and works well, but seems to cant the muzzle outward, so concealment isn't very good. I bought the 565BL and the UBL High Ride...both seem to work very well, with the UBL High Ride being a bit more comfortable. Both the 565BL and the UBL High ride are higher than my mid-ride holster I had on Patrol. HUGE improvement when sitting....
The 565BL and the UBL High ride are SLIGHTLY different in ride height. IIRC, the 565BL rode a tad higher than the UBL High ride. The UBL High ride was a tad more comfortable though. I'm still bouncing between the two trying to see which I like better.
HOWEVER, I did just get the DeSantis TacLite Holster. My Agency has a requirement that we have either Thumb-breaks on our leather, or the ALS/SLS on our Safariland holsters. After exhaustive searches, it seems only DeSantis (TacLite holster) and Safariland (with their "REVEAL" Holster) make leather concealment pancake holsters with retention (thumb-strap) for G17's with the Streamlight TLR-1's. The TacLite is VERY comfortable, rides higher than either the 565BL or the UBL High Ride, and is VERY concealable, even with the full size G17 & light! (albeit I do wear a fleece vest to help conceal).
LA Police Gear has the 565BL's for like $10. Grab one and try it. Can't go wrong for that price. Either way, the 565BL or the UBL High Ride will definitely make a HUGE difference when sitting in a patrol car
PS: I'm a lefty, so didn't have the issue with the console...but DARN if it didn't hit the seat and ride up and dig into my side!
