Kahr PM9: 6+1 capacity with other mags available. MK9 also available.
It's a step up in quality.
Just because it's small doesn't make it good for the purposes of effectively fighting. It just means it's small and harder to use.
Additionally, Frank mentions several other defects with the PF9. More nails on the PF9's coffin.
Regarding the training posts, above: I think what the posters really meant is that a gun is not convenient. People try to turn this into something convenient. They get fat and expect the gun to "protect" them, as if it were a magic talisman to ward off evil. In the end, it's about fighting. Fighting effectively requires fitness, mindset, tactics, and appropriate tools. The world's smallest 380 pistol is all fine and dandy, but it's not the only trick I'd want in my bag if I were out to kill goblins*.
* THR Nannies: Fighting is what it's about. We'll say certain things in court, such as "I was shooting to stop him". However, the reality is lethal force is LETHAL for a reason: it's an attempt to kill. We dress it all up for presentation in court, but that's all. Call it for what it is and keep the courtroom phrases for that audience. Unfortunately, too many people insist upon hiding behind the reality of this by using the courtroom language exclusively.
