Had the 4 inch base model in blue/black for a while last year, bought it in Pittsburgh for $179 NIB, but most people seem to get the 5.5 inch. No jams whatsoever, just some misfires with Remington Goldens, wife loved it, her best friends 7 year old was introduced to pistol shooting with it and needless to say loved it too. In fact come to think of it, everyone who handled that pistol loved it.
I have heard of people carrying the 4 inch for CCW which is a little excessive, we took it hiking with us (errrm that is we COULD have done if it wasn't illegal) but I wouldn't want to carry it holstered.
Some people say it's has a cheap feel, but what do you expect for less than $200 (I used to be confident saying that but now there is the Walther P22 of course).
Were it not for that incredible new Walther I would get another, but my next handgun of any caliber will be the P22 and I haven't even seen one yet.
