Hopefully that is the last we'll hear about the alcohol issue. Let's just drop it, everybody. It turned into exactly the kind of useless soap-boxing I had anticipated, and I am as guilty as any of helping to point the thread in a non-productive direction.
I want to get a pistol soon as well so that I'm proficient with it by the time I'm old enough for ccw.
1.) Is .45 not a good starter caliber, should I start with 9mm?
2.) Does anyone object to a Glock 21/19 as a starter pistol?
Regarding the 9mm vs. .45 question:
The 9x19 caliber is one of the very least expensive to shoot, if this is a consideration for you. As I'm sure you know, in most handguns of equal size and weight the .45 will recoil a bit more than the 9mm, but not so much that it should be the primary factor in making the decision between the two, particularly when chambered in mid- to full-size guns.
Ideally, you should find a way to fire a couple models in both calibers before making the final choice (have you? I'm not sure I read every one of your posts after the original one). But with a superb gun like the Glock, I think you could buy one outright with almost no chance of being disappointed. They are fantastic firearms, and soft shooters compared against many other manufacturers' models in the same calibers.
Were the choice mine, I would pick the G19 over the G21. It is one of the best all-purpose (though not for hunting, of course
) semi-autos made. It should be a great learning gun; if my G23 (.40 caliber version of the G19) is a sweetheart to shoot, the somewhat less powerfully chambered G19 should be that much more pleasant.
