As far as I can tell, the only real difference between the SLS and ALS, is the addition of the "Sentry" to the SLS system behind the hood. Thanks again.
The ALS is for auto locking system - Its the sls + the auto lock - which is different than the sentry. You can actually have the ALS with Senty - which gives you level 4 retention (cant imagine how that would be to draw from).
According to this site: http://www.copsplus.com/prodnum6247.php they have ALS for an MP45/light.
