For those of you unsure of what frangible ammunition is, do a google search for Glaser Safety Slugs, or MAG SAFE ammunition.
That should explain it to you presently.
As for my bedstand gun, it is a 4 inch Smith model 19-5 357 magnum loaded with glaser silver 38 special frangible rounds.
It is, however, NOT what I carry on the street.
And another thing while I am at it.
The 9mm is only a mousey, underpowered round for those folks limited to full metal jacket ball ammunition.
There are many rounds out there that are close to, or as good as 357 magnum ammunition.
Chosen properly, it the ammo is nearly or AS good as the new flavor of the month handgun round that all the police departments are wanting to go to..the 357 SIG.
Mine: 6-inch S&W Model 66 .357 with Federal 130 grain Hydra-Shok rounds. I don't trust frangible rounds because they give lousy penetration; a surface wound is not going to stop a determined attacker. I want bullets which can make gaping exit wounds.
Next pistol will be a Sig Sauer P220 in .45 ACP.
