Just a suggestion if you don't do it...keep a journal of the ammo you shoot, any drills you do etc.   I've fired about six different types of ammo, Federal hi shock being the most accurate.  Freedom munitions also shoots very well.  Federal aluminum case shoots the worse, followed by Remington green&white box.  No malfunctions with the glock so far, but had some interesting malfunctions with my issued M&P and it was nice being able to explain which magazine, etc when it would malfunction.  Like I said, just a suggestion.

I'm about as far from being a Glock fan as one could get.  That being said, the G19 is a damned fine pistol.

It's the perfect size for carrying, le, shooting for fun, etc.  It does everything well.  

When people ask me about pistols and don't have any definite likes or dislikes, I recommend the G19.
