I held one at a local gun show, and I WANT ONE!

I know it looks awkward to hold, but it isn't. Your hand fits right into the grip and the trigger is easy to reach. It's amazingly light and compact. It doesn't seem much bigger than a large pistol. It's hard to believe Kel Tec stuffed a 16" barrel into that little frame. The sights, ugly as they look, work just fine. You'd think your thumb would be in the way of the sights, but the sights easily clear the top of the gun. And they fold flat and out of the way.

Ergonomically, the gun just works. One day I'll shoot one, but put me on the list for ownership soon. I'm hoping the prices will drop some as they become more common.

I'm interested in one, but later adding a pistol grip to it.

I like the shape. Kind of the same stock concept as the FN P(S)90.  It keeps it non bulky.

I wanted one, but settled for a regular RDB, which has been nice. Once they're caught up I might even buy the survival stock to try it out, but I'll probably be bored with it by then.

I want one, but with a pistol grip. Can't say I'm a fan of the California compliant stock.

The survival stock is made to be shorter (height) and lighter, more of a traditional rifle style. While nowadays it's common to think of that as "Cali compliant", the Survival is NOT cali compliant. The stock has a collapsing element to it!

There IS a RDB Cali model. Longer stock, no collapsing, 20" barrel with no threads I think.

My main complaint with the S is that the front sight is on the threads, so the sights would be useless to me.
