Neither the CZ Rami or the P239 is actually slimmer than my G26. But if the grip is better and I can reach the trigger more easily, I'd go with them.
The Rami looks pretty sweet. I've never seen one before! As for the P239, they seem to be non-existent in stores for the past year or so! I plan on holding both, but it doesn't seem like that will happen anytime soon.
Not for sale today!
