Thank you for the tip, and thank you for your service to our nation. Salute!
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.
