Has anyone here tried/own the AlienGear IWB holster? I've seen some pretty good feedback on them, and the price, deal, guarantee etc. seem really good. I wondered if anyone has their own opinion/feedback? https://aliengearholsters.com/ ~$30 to buy, 30 day money-back guarantee, free shell change-out for life, full life warranty, quality parts etc, seems *very* promising.
