sorny-
If I can offer my .02 on the Kel Tec. I had a couple Kahrs. They were ok if you are patient and get them broken in, but not what I call rally Pocket size either. I really like the Bersa Thunder ($220. new in two tone) too, but it is not in the same size and weight class.
I decided to get a new 2nd gen. KT P3 in .380. I have about 400 rounds through it and am happy with it. I asked for a new extractor and spring which gave me solid ejection even after 50 rounds got the gun dirty. Borderline problem as a pocket gun, but it now goes well over 100 rounds before the barrel/chamber need a light cleaning. The new extractor shape is likely on all new ones now this year. I have noticed the new P3 in Hard Chrome is pretty trouble free as another choice.
I said all that to say this........
After alot of reading about many Pocket guns- IMHO
you must keep them clean. Truth be told, I notice many people expecting too much from an intense little design. So I think any pocket auto can use a close look for rough metal in this price range and frequent cleaning/lubes and they work.
I usually buy used guns in any brand and have never been disappointed when I apply some patience, cleaning, a bit of polish, and at times a warranty part. I think some products get a bad reputation unjustly.
I could go on with other recent used purchases of late by me and some friends but the theme is the same. Pocket Automatics are a small machine and need to be maintained and tested before you can fully trust them.
Now that used Glock I got lately cost much more than a P3, looked like new,is a lot bigger, and has a barrel and chamber like glass...it was rock n roll out of the box
