Keep in mind, there are different lines of ALS holsters. There is a much lighter CCW or "sporter" version which comes with a paddle as well as a belt slide IIRC, as well as a variety of much heavier level 2 or 3 duty holsters which are very pricy.
The one I have in mind is the Safariland 6378. Safariland® Model 6378 ALS® Paddle Holster
They also offer an optional guard that installs over the release mechanism that essentially makes it a Level 3 retention.
