I have not had a chance to shoot all the weapons mentioned, however, besides my small collection of CZ's for a CCW I've aquired both a Kel Tec PF9 and the Ruger LCP and can comment on these. Avoiding the debate of a 9 vs a 380 while both can be carried in the front pocket of a pair of Levi jeans the PF9 IMHO is sort of the the maximum size and not as comfortable. Clearly the little LCP is much easier to conceal and is almost unnoticed (by me) in my leather "Indy" jacket that has A2 flight jacket type pockets, the PF9 conceals easily but "I" feel it. I have both rigged with lasers an ArmaLaser for the PF9 and C/T for the LCP. I tend to carry the LCP much more often as it's just much smaller and much easier to conceal which for me is the most important thing. I have an IWB rig for mt PCR and while I can conceal it, not being a LEO it's not what I would choose to carry on a day to day basis just too big. Clearly the PCR is much more comfortable to shoot, however, the PF9 is really not too bad at the range, has real sights and has been very dependable for me. Also keep in mind it cost me about $270 for a chrome slide version so the investment is also none to steep. Now the LCP is a bit mor punishing at the range even a little 380 kicks in such a small package and the sights are tiny. Some say it's a SHTF point and shoot type weapon, clearly it's no range queen. I have the C/T laser and the finger extension which really helps and I'm pretty confident I can be effective to 10 yards or so but it's not a gun one wants to shoot much, it's a mouse gun that is easy to carry and hide. For me again, concealment is the top priority so the LCP is my usual choice. In a "Smart Carry" or "Thunderware" type rig one would have to be goosed to find the weapon. Now for a LEO it makes sense as a BUG unless one is going for deep cover but for the average Joe (not the plumber) who is looking for a pocket pistol that can be had for (I paid $260) a reasonable price it is worth a look, mine has also been very dependable. True Kahr makes a fine gun and if you got the bucks and are willing to pay for it I'm sure there new 380 is great. Bersa is also recommended by many but it is a much larger gun but it really depends what you want, a larger gun with bigger grips would tend to be easier to shoot but ain't going to slip into a front pocket like a mouse gun. While I'd say there is little question that both my PCR and PO1 are higher quality than either the PF9 or LCP there is also the logic should one ever have to fire ones weapon in self defense you will probably have to turn it over to the Police and it sure would break my heart more to give them my CZ than the little ElsiePee. Bottom line for me is the LCP is very easy to slip in my pocket with a Superfly holster, no muss no fuss. I've said this before, I'd really like to see CZ come out with a small single stack 9mm and would like to see what concept CZ would evolve if they considered to produce a "mouse" pocket pistol.
