It is a point and shoot gun-you aren't going to need that much training with it.
I fundamentally disagree with that statement. When someone is trying to kill you or do you serious bodily harm it is a very different situation than when one is standing at the range calmly shooting holes through paper.
When that small auto has a jam when you are facing death how much thought do you want to need to put into how to clear it? You don't want to need to put in any thought; it needs to be a reaction.
When someone is coming at you with a knife is not the time you want to learn that you cannot quickly draw because your pockets are too tight or that your pocket holster snags the pistol or that the holster comes out of your pocket still on the gun. when you are fighting for your life is not the time you want to realize that you have never fired a shot from a retention grip or off of your back, or with your weak hand or ....
When one needs to pull out a pocket pistol it is a safe assumption that things have really gone south. It is a time I want to have practiced to the point I am reacting not thinking of solutions. The types of scenarios that require use of a CCW (and perhaps a small pocket pistol in particular) are unexpected and unfold rapidly. If not, one could remove themselves before the trouble started. Again this means it is not the best time to be trying to figure things out or remember how they ought to be done. It is about having ingrained things to the point of reaction.
I'd put rounds down range with a gun that will actually allow me real feedback of my shooting skills.
I put rounds down range with the types of guns being discussed in order to develop the skills needed to effectively use them for their intended purpose. I am not shooting for groups with my snub nose or pocket autos. Training (and this is true of more than just guns) should be done with ends in mind. The point is not merely to shoot a lot for the sake of shooting a lot it is to develop particular skill sets.
Situations can very quickly require skill sets above and beyond point and shoot and when the time for action has arrived the time for preparation has passed. Even point and shoot is not as simple as it sounds when one is discussing a real gun fight. As I wrote above, there are many videos one can find on the internet of people unloading a magazines worth of rounds at each other at spitting distances and no one getting hit or similar such scenarios. Of the videos I have seen a number of them are LEO shooting full size duty guns not tiny pocket pistols.
Practicing with these types of weapons may not be all that necessary in the same way that carrying a gun is not really all that necessary. Odds are you will never need it anyhow. That said I prefer to carry and if I am going to carry a weapon I prefer to be as proficient in its use as I can be. Proficiency and training/practice go hand in hand.
