Just my opinion but I don't think the new "slim" KelTec will have any effect whatsoever for those who were considering the purchase of a Rohrbaugh pistol for concealed carry.
I think that the initial price of the Rohrbaugh is simply out of the price range for the "average" pistol buyer. I'm not saying the Rohrbaugh isn't worth the price, I'm just saying I don't think most folks can drop $1000.00 (more or less) on one concealed carry firearm.
I personally feel I "got more for my money" with a S&W J-frame 638 (Bodyguard) w/ Crimson Trace Lasergrips AND a Keltec P11 (or P32, I have both). If you shopped carefully you could probably get all three for $1000.00.
My experience with all three has been nothing but positive, and in fact the Crimson Trace Lasergripped J-frame snubby is very, very acccurate, and absolutely reliable.. (As the nature of the revolver seems to be.)
If my boat ever comes in, (and I don't think it's out of drydock whereever that is) I would probably buy a Rohrbaugh for the same reason that I would like to own (but cannot afford ) an H&K P7M8, or Walther P5.
Quality, and exclusivness...
Even then I would start lobbying Crimson Trace for a set of lasergrips for it. Those lasergrips ARE well worth the money.
Just my old (seriously poor) fart opinion.
Best Wishes,
