I did a search on PF but could not find any previous posts on the topic.
I have tried out a Safariland 7TS ALS holster for a Glock with a SF X300U WML (equipped with the DG-11 switch). Only the retention was abysmal. The gun would fall out from the holster if inverted, and given a very mild shake. From a normal carry position (aka not inverted: ) the gun could be plucked from the holster by gently rocking the gun back and forth. So: abysmal retention.
For work I regularly need something like an ALS holster with a WML, but I could not rely on the holster to retain the gun, so I threw the holster in the trash.
Now: is there a remedy for this? Going to a Level 2 ALS holster?
