Now, something for those complain not be able to holster an airsoft pistol with a tacligh attach. This Big Dragon version costs US$22 at Airsoft Panda... "Finally, an answer to the thousands of requests we have received for a SERPA duty holster that works with a pistol light. Now that the Night Ops Weapon Mounted Light has solved the issue of blocking the trigger guard, you can get the Level 3 SERPA holster, noted for its speed and retention, to wear with a light while you are on duty. Outstanding retention, extremely fast draw even under stress and immediate lock-in upon reholstering. Now you can have it all."

We're sure this text at Airsof Panda came from the SERPA holster product page, most likely from the  LA Police Gear Page.
