I'm thinking about giving AIWB carry another try.  A while back I did a bunch of research and ended up getting a JM Custom holster, but I just couldn't seem to conceal it that well.  Lately I've been looking at the Incog Eclipse, TREX Arms, and the Eidolon, but I'm leaning toward the Eidolon.  Any reason not to get one?  Is there a better option?  The reviews I've found thus far seem pretty positive.  Will be used with my G26, possibly a 19.  Thanks

Do it.

I have the G17 Full Kit and the G19 Ambi Basic Kit.

I love mine.  I used an Incog for a while, raven vanguard II, and a t-rex side-car style holster (not an actual t-rex brand).

Eidolon is my favorite.  I have the wedge and claw on it and it carries very comfortably, and conceals great.

Of the options you listed, I would go with the Eidolon or Trex. I waited around 7 weeks for my Incog, and it conceals horribly on me. It is a really nicely made holster, but I don't like how it relies on the tension against the clip to conceal, just didn't work for me.

After that I tried the Eidolon, and it conceals really nicely and is comfortable. I actually broke the sweat guard off of mine in defensive pistol class, and it was quickly replaced under warranty with a new unit.

I currently carry Trex holsters, both the sidecar and the raptor models. They conceal well for me, and have been durable. Full disclosure: I have heard of one or two people having the claw break on a Trex unit. However, I have more than 5 of his holsters, and have carried them daily and run them in classes with no issues.

I have the Eidolon for my G19. I got the agency package. I utilize the wing, wedge and the soft loops. It wears surprisingly comfortable in the AIWB area. It conceals extremely well. I can wear a fitted t-shirt and still conceal the G19. I have the T-Rex Arms Raptor for my Springfield XD Mod 2 (a lot small than the G19) and it conceals that firearm extremely well. I also own 2 INCOGs. One for the Springfield XD Mod 2 and the other for a Springfield XDS 9. Both have the mag caddies. The XDS is easily concealed. The Mod 2 not so much. I highly recommend the Eidolon for the larger sidearms.

Thanks for the replies.  I went ahead and placed my order for the Eidolon.  Looking forward to trying it out.

Eidolon is good.

Got my Eidolon in the mail a couple days ago. I'm using the wedge, claw, and just one soft loop on the claw side of the holster. I'm liking the setup so far.

I really like mine as well.  I have been wearing one since they first came out.  It took some getting used to but no other holster I own conceals was well as the Eidolon.  I like the fact that its cut for an RMR and suppressor sights as well.
