My brother in law was telling about this ammo. Anyone know about this or tried it before?

As long as your assailant is kind enough to face you sholders square, isnt wearing any heavy clothing, and his arms are not in front of his torso like they would be if he was pointing a gun at you. It might penetrate enough to hit something vital.

12 inches is generally considered the minimum to rely on the bullet to penetrate appendages and the torso at odd angles and still reach the vitals. Magsafe and other pre-fragmented ammo do not meat that requirement.

"Magic" bullets generally aren't.

I personally do not believe in any magic bullet because there's no such thing.

There's no way that we can burn water without separate the hydrogen and oxygen. If someone found a way, the world would just change.

Same thing applies to every other scenario in our life. If there's some magic bullet that performs so much better than Federal HST and Speer Gold Dot, the world would be all over it and every law enforcement agency would adopt it.

The thing is, there's none. anything that claims to be one has not gone through all the rigorous tests like all other true performers have.

Me either!

I have never used Magsafe, but have a lot of faith in their competitor, Glaser. I do not feel there is a lack of penetration from them and have tested the penetration of Glasers. From the site posted by Frost, the Magsafe round penetrated a 4 inch block of ballistic gelatin, traveled 10 inches, penetrated a rack pork ribs, then went an average of 4.3" through a second block of gelatin. I disagree with their position that this is not sufficient penetration. How far into your chest is your heart, after the rib cage is penetrated. And their test was set up to assume a flesh wound in the arm where the round had to penetrate the arm to get to the chest.

I agree that there are no magic bullets. No one claimed that these were magic and would end a gun fight. These rounds are marketed as being as effective for stopping power as any other round, while having a lower liability potential from over-penetration, ricochet, or miss going through a wall. I agree that they seem to meet these standards, and do so well enough for me.

I do not carry Glasers very often and will not carry Magsafes for the same reason I think most police departments do not. Police agencies do not flock to them due to their lack of effectiveness, but for several reasons. One reason might be just the opposite of what was thought. They may be too effective and no police agency would want the public relations nightmare of bullets designed to kill more effectively. I would think the biggest reason most agencies stay away from them due to the cost. They are very expensive, especially when you try to buy 50 rounds per officer for say the 300 officers in my agency. Police agencies make decisions for many reason that have nothing to do with effectiveness, and cost is probably the biggest reason.

After a little research last night I believe I'll stick with JHP on my shelf. I do have a better understanding of how this ammo works but the cost is high.

I have experience poor accuracy results (beyond bad breath range) with both Magsafe and Glaser. Flash and blast can be quite impressive with both also.

Pun?

I had similar questions about MagSafe ammo about a year ago for home defense usage. Upon researching the ammo's ballistics, I ultimately decided to stick with a conventional JHP load for home defense purposes. At first blush, this ammo seems like an ideal solution to the "overpenetration through sheetrock" issue. However, MagSafe appears to really underperform (i.e., underpenetrate the target) in ballistic evaluations when compared to conventional JHP loads.

Additionally, MagSafe and the similar Glaser ammo are simply too darn expensive for me to keep loaded in any of my guns!

Maybe if I were a Sky Marshal, I'd have a different opinion...

Sky marshals cary 357sigs. Overpenetration isn't one of their biggest concerns.

Some of those lightweight bullets may not reliably cycle your gun. They're also real expensive so how much are you going to use up in practice and reliability testing?

Stick with a proven jacketed hollowpoint from a major manufacture. Gold Dot, Ranger, HST etc.

Good point, given their choice of caliber, it must not be an issue that they consider! If there is a round that could potentially overpenetrate a target, it's that little high-pressure caliber. Although with pre-fragmented ammo, this risk is greatly minimized.

I find the .357 Sig to be an interesting round, but the ammo is prohibitively expensive. I'd also imagine that the "necked down" cases would ensure very frustrating work for reloading purposes. The cartridge's impressive ballistics can be more affordably replicated with 9mm +P+ ammo.
