Yeah well not everyone here is super instructor level 10 with your SCAR17 and HK snobbery. Some of us are basic of the basic and just wanna open carry at the range.
Nobody said you needed an expensive holster, just that the SERPA is terrible. You can probably poke around on Amazon or wherever and find OWBs for $60 (actually strike that, probably $30!) or less that are 10x better (and safer) than what that thing is.
There's "basic" and then there is "unusable".
