Hi, Onechance. I don't know if this will be timely, but here's my welcoming info.
I love my Mag-na-ported P40 and Glock 23C, so I know it's a great cartridge and only you will know if it's too much of a hand-cannon! For the range the PPU .40 180-grain TMJ is the "weakest" factory range ammo I've used. The other stuff is like .357 magnum loads next to .38 special... sort of.
Welcome to the Kahrtalk forum supported by K a h r Arms.
Here are a few essential links and things to do BEFORE you take your new pistol to the range, and ESPECIALLY BEFORE taking it apart and trying to re-assemble it! The Kahr is a different design… 6-7 unique patents cover the Kahrs. I’m not trying to imply that you don’t know anything about guns, but many don’t know anything about the Kahrs and some of the things you can do to damage or cause malfunctions of your new, or new-to-you Kahr pistol.
First, if you don’t have a manual, yet, or one didn’t come with your pistol, you can view it and/or download the pdf file here:

Please watch one of these videos FIRST! These videos can point out possible problem areas and emphasize correct procedures!

There are many links on fixing problems listed in several places… under the New Member or Kahr Tech sub-forums. To start, a very good one:

A very handy one is the Kahr Lubrication Diagram:

Many of your questions can be answered in these areas and you can learn how your Kahr works and not damage it with improper handling.
Another great resource for information on Kahrs... Archives of Magazine and Internet Reviews for Kahr pistols by industry experts. They test these pistols and report on their views and the ammo they tested in it. This is a good way to find ammo that might fit your needs along with accuracy and feeding in the pistol... usually from a rest with velocity and energy, as well as penetration and expansion sometimes... very informational.

Frequently asked questions: http://www.kahr.com/faq.asp?
One very important bit of advice: Hold the Kahr pistol firmly when firing OR CHAMBERING a round. These compact pistols need all of the force they can get from the slide to get a round into the chamber successfully. If you don't hold the pistol firmly, part of the needed momentum is transferred to MOVING THE PISTOL and the top round will DIVE and jam into the right side of the feed ramp. The weak hand, over hand rack method gives the best grip and a firm rack will give you the best chance at chambering a round.
Use the weak hand fingers over the slide(clear of the ejection port), thumb along the slide and pointing to the rear. Use the gun hand to simultaneously firmly push the gun as you give a vigorous rack with the weak hand and cleanly release the slide as it reaches the rear limit and is "snatched" from the weak hand. This approximates a real rack from firing and beats the slide release method WHEN executed properly. Much more strength can be exerted when this is done closer to the body.
Here's a video on that. The first part is what I'm talking about:

There are many helpful members here most of the time who might be able to help you, but as anywhere, there are many opinions and not all are correct. Be mindful of this before doing anything drastic to modify your pistol!
