I got out there today! They have a great facility, it's really cool that you can bring your own steel and set up your own bay. Took a video of me shooting one of the stages. There were less than 10 other people out there which was a nice low-key environment. I missed quite a bit, I'm definitely noticing that my trigger press is messed up unless I really focus on it while under time pressure. I also bungled my last reload, couldn't get the empty mag to drop out.

Thanks for the advice! I've had good holsters made by JM Custom Kydex for both my handguns in the past and I know they make mag carriers. So when I get around to buying more magazines I'll probably start using their carriers. The Esstacs will end up being used for hiking/hunting/outdoor stuff, I might look into doing those Run N Guns too, that sounds like a lot of fun.
