I will say also this... I ordered an Alien Gear Cloak Tuck IWB for my G23 early in the summer... after my order was confirmed, they sent me an email stating they charged me the order total, and that it would be 4-6 weeks wait. I was pretty missed, replacing the M with a P to make the real word. It took them until the 7th going on 8th week to get it here... during that time, I had already decided I would need a dedicated EDC pistol and wanted to buy the Shield. I got the Cloak Tuck holster for my G23 and tried it, it was nice, but still... I needed a Shield.
When I went to order a new good and primary holster for my Shield, I was so missed with a P at Alien Gear , I skipped the idea of ordering another Cloak Tuck or even the newer Cloak Tuck 2.0 holster and went with the Galco King Tuck IWB... it was like an exact style of the Cloak Tuck but, different. It was a lot smaller and more petite of a package, with rigid plastic as the shell and rivets instead of the adjustable Allen-key screws used on the Alien Gear.
As it has gotten cold in FL finally, I have started incorporating my G23 into my carry rotation. From Aug through Nov, I carried the Shield every day, all day, generally in the King Tuk. Well ... let me say this: I really am liking this Alien Gear holster more and more. Despite the fact the G23 is like double the gun that the Shield is, it's at least as comfortable as the Shield because this is really a nicer holster. it just feels better, I like it a lot. I think that the Shield would be AMAZING in one of these holsters. Am I going to get one? Doubtful, because my $57.57 Galco King Tuk does the job and does it well enough. But, still, I am more sold on the Alien Gear Cloak Tuck and recommend it to others.
I really don't care for the PEOPLE of Alien Gear, as they were dismissive bamboozlers as far as I'm concerned... but their prices are amazing and their product awesome.
