Though I'd update on my blue line concealment. VERY satisfied. I've been carrying my VP9 almost every day and it is as comfortable as I can imagine a full size gun being.
Just got my IWB appendix carry holster from Will Silk Custom Kydex for my G27. Love it so far. The guy is super nice, good product, fair price, and local.
I have 3 AIWB "grab n go" holsters from Rubicon Tactical, Ruger LCP w/CT laser, Sig 938 and Sig 232SL. His design completely covers the slide, better than a "sweat shield" and protects the gun better from moisture and bumping against something which may scratch the slide or, in the case of the Sig 938, deactivate the safety.
Greenforce tactical is great. They have 4-5 different appendix holsters in the ready 2 ship option.i got it in 3 days nice not to wait regular custom kydex time. The alpha g19 is super comfortable and minimal material for a great price and fast shipping
