I've got the chance to pick one up for $400 out the door. What do you guys think??? Buy????

good deal!

I bought one for the wife years ago.She has smallish hands,and the kahr fits her perfectly.Untill she shot about 100 rnds through it,it would sometimes lockback the slide even with rounds in the mag.Pretty accurate,and nice sights for essentially a pocket gun.Sounds like a good price.

Bought one for my carry gun. Love it. Never had a problem with it, it's light, it's accurate and in my opinion it's the perfect carry gun.

I think it's an excellent gun for when you can't carry a gun.  Mine gets carried sparingly.. but it's when I really can't have even a compact gun.  It fits that need for me very well.  I feel quite confident with the 9mm caliber... and while I know there are smaller and lighter pocket guns, this one does everything I need to for a serious hideout gun -- not too expensive, small, and in a good fighting caliber.

I've had a few issues with failures to feed, and recently a few issues with the slide locking back on a non-empty magazine when shooting +p ammo (JHP) that has bothered me a bit.  I've only got about 500 rounds through it.  According to my calculations (and I keep very detailed records), it's just over 98% reliable.  Not stunning, and something I want to watch, but nothing that causes me to lose sleep.  The slide locking back thing is something recent in the last 100 rounds.

It's combat accurate to 50 and 75 feet if I do my part, and certainly is more than effective at true self-defense distances.  Which is miles and away better than my dad's keltec, which we can't seem to figure out where it's hitting at 7 yards (seriously).

I'm not selling mine and have had it for about a year.  It fits its role quite nicely.

I have pondered this same purchase issue.  I've heard too many bad things about Kahr in general to take the leap...

S&W J-frames have never let me down...

I would like to pick on up myself, but there are lots of posts on various forums about them choking.  The frames don't inspire confidence either.  If Kahr would make these with aluminum frames they would have a winner.

Quoted: S&W J-frames have never let me down...

+1 on the J-frame.  It ALWAYS goes bang.....

I have had one for a couple of years and never really warmed to it enough to want to carry it.  Hard to explain - I guess I think the concept is good, but the execution is ugly, hard for me to shoot, and seems to me cheap and poorly made in the hand.  Or maybe its just me.

I carry mine every day. YMMV.

I have a S&W 642 and just bought the economy CW9 factory refurb. for 319.00.  I put it in a Milt Sparks Watch 6 and it carries like a dream.  I at first thought it looked a little cheap as far as the internal finish of the weapon and a little sloppy on the polymer slide cutting, but after I shot it I have complete confidence.  200 fast rounds at the range and not 1 problem at all.  Shoots great goups and once you get used to the trigger it is friendly to use.  
As for the 642 well not a darn thing wrong with it, just depends what you like.
400.00 is a good buy. You should get it.

For me, 642 > PM9.  YMMV, of course.

I had one of the very first PM9's and put many rounds through it. liked it so well I sold it for my current carry favorite, the all black PM40 with night sites. After the recommend 200 rounds to fully break things in they both ran perfectly. I'd do it again.

i wouldn't count on it till you've put at least 500 rounds thru it. seems like it took that long before the SO's began feeding reliably. once broken in she hasn't had a problem. YMMV

i carried her PM9 instead of my G19 yesterday. very comfortable, way more than my glock.

I have a P9 and a PM9. I'd rather shoot my H&K's, but I almost always end up carrying the Kahrs.

If you have large hands , you may find the PM9 to be a little too
small to grip effectively . I traded mine for  K9 which fits me much better .

I've put about 800 rounds through mine.  It has never given me a problem and feed all types of hollow points.  

I love my PM9, but after the 200 round "break-in" period, it still had issues that required smithing-up.  After getting it back form my smith, I've had absolutely no failures through a few hundred more rounds.

I like stainless steel on CCW guns due to the closeness to body produced  humidity and salt.

This thread was very good for me but very bad for my budget.  I just put a used PM9 on lay-away.  After tax it will come to less than $370.  I would rather have the covert but hey for that price I will carry it inside my waistband instead of in my pocket.  

I really love my PM9.  It has run flawlessly for 500 rounds or so and that includes several different types of hollow points.  Hopefully you will have similar results.  

+2 on the Jframes....go with a S&W 340PD scandium(357/38+P) weighs about 12oz and always goes bang
