I really don't think that what the L.E. crowd uses, or doesn't use has much to do with this discussion. I haven't worn a badge in nearly 19 years, but I still want the best fighting tool I can get. I think my own hide deserves that. And, I am definitely not interested in pursuing felons or solve extended situations. I'm too old, and uninterested. I'm just interested in protectin myself and my family, and as far as "getting away safely", I am all for that, except I can't run, I'm too old and beat up.
As far as "debatin" what will take down a "hopped up meth head", there is no debate. I actually know what will take down a "meth head". I also know that "hopped up meth heads" break into homes, rob businesses, car jack citizens, and mug and kill innocent citizens. I also know that a properly applied 12 gauge pump WILL take one down. I've seen it done. But on the other hand, I've seen some folks that were "leakin" pretty badly, that kept comin, till they were all "leaked out".
Now at my age, I hope I never have another encounter with a booger. Meth or not. But if I "must", I hope first he is, fallin down drunk, stupid, blind and in a wheel chair, and armed with a 380. With the new defense ammo of course. Any of the aforementioned will give me my edge. I will be carryin a 40, and I hit where I aim. Even under pressure.
Got your email OldShooter. Major caliber is anything ABOVE 9mm. My vote is "major caliber" in what ever you can handle and hit with.
