I just purchased the Safariland 6378 ALS Holster. It works perfectly with my Crimson Trace Lasergrips.
The Safariland 6378 ALS Holster comes with both the "Belt Loop" and "Paddle" options.
It also has the same locking/retention system as the Blackhawk Serpa Holsters, but the release button is hidden and can be activated while wearing thick heavy gloves on those cold winter nights.
I needed a retention holster that also accommodated the Crimson Trace laser grips. I'm really glad I found this holster.
Pros: Works perfectly with Crimson Trace Lasergrips
Cons: None
