Glaser Safety Slugs, "exotic" handgun rounds...
The Glaser line was sold in the US market in both a blue & a silver model(slightly more powerful & a different design). When CorBon bought Glaser, they changed the line and to my knowledge, only sell the "blue" type Glaser Safety Slug.
I for one see some merit to the use of exotic or special purpose rounds like Magsafe, Glaser Safety Slugs, TAP rounds, etc. For larger calibers like .44magnum, .44spl, .41magnum these loads can prevent over-penetration, riccochets and other hazards in places like apt buildings, office complexes, malls, etc.
By my state law/policy, armed security-PIs can not carry or use "fragmented" rounds like the Glaser Safety Slugs while on duty. I asked a state panel member directly about why this restriction was made and he told me it was due to the low production standards & lack of quality/uniform performance.
I take issue with that state policy but I can understand the reasons.
I bought a few packs of ExtremeShockUSA .38spl about 6 years ago. They were pushed by the US gun press as a great protection-duty round in the post 9/11/2001 counter-terrorism world. I didn't think the ammunition was all that great and wouldn't be in a huge rush to by more.
As posted by other members, more popular factory brands & JHP styles can do just as well or better than Glaser Safety Slugs.
