The CW45 is pretty sweet. I've handled one, liked it a lot. I have a few carry pistols in that size class in .45 & 9mm, so don't really have a burning desire for one. The 22/23 would be much more useful as it has a few advantages over the Kahr. Concealability is close between the two. For me capacity, multi caliber conversion capability, ( .40/9mm/.357/.22lr) & proven reliability in an adequate caliber. Tons of inexpensive aftermarket and factory replacement parts available that are easily owner installed. Ah shucks, buy both!
Last I checked, the "Happy Sticks", were about $40. Haven't looked for any for a while. I think I saw some in the Blue Press for about that price. Just check around, I see them advertised in a lot of different places.
Good Luck,
Savage
