Used my new holster for the first time today in a training class. The class required a lot of moving around and different shooting positions i.e., standing, kneeling and laying down. My pistol stayed secured in the holster till I was ready to use it.
Very well made. Haven’t really had the chance to run it yet but I use the conceal everyday and it fits well and stays in place even when you draw the firearm.

This holster is awesome! Not many options for Icarus precision customizable side cars out there, had never heard of this company prior! Man am I impressed by the overall quality of this holster! Far more adjustable than anything else I’ve tried in this style(Tier1, Trex, LAS). I’m still adjusting to exactly how I like it about 2 weeks in. Only complaint I found is my optic (Swampfox Sentinel 2) did not fit and I did have to remove material around the optic to make it compatible. I know this isn’t a common optic so I wasn’t worried about it at all! Highly recommend you go buy this one
