A 9mm HP "MAY" expand, but a 45 FMJ will never get any smaller!!
Ya know, I never thought of it that way. That is a good point.
Since the politicos in this 'wunnerful' state have yet to realize that people should be able to defend themselves from criminals, I dont carry on a day-to-day basis. But I have run HP's thru my Sig P220 quite a bit, and it worked just fine. The only problems I have ever had with the Sig were when using Wolf ammo. I wont use Wolf in my pistols any more, but it still gets fed to the rifles.
If one .45 FMJ wont stop him, I got at least 6 more. One of them is bound to stop the sumbich.
This is, IMO, another one of those 'whatever works for you' things. If your weapon will work just fine with HPs and you want to use HP, by all means go for it. If you dont feel comfortable using HP in your weapon, use FMJ.
I wonder, though, how effective that Glaser Safety Slug is? The one that has a bunch of shot pellets in it? I dont know if its the same as the Glaser ammo I had read about somewhere else, that was saying that a large % of people shot with FMJ live, but the vast majority shot with Glaser ammo die, as they induce a LOT of shock right friggin NOW! It wasnt in a gun rag that was trying to sell Glaser ammo. I dont remember where it was. I do remember thinking that I'd like to have some of that stuff, though. Anyone used it? What did you think about it? Hype, or good stuff?
