First of all, I am glad that the patient is alive. Human life is important and precious. Mankind only lives once and then faces judgment.
However, I'm not a fan of frangibles by any name - whether that is Corbon, Liberty, G2, etc. I wouldn't dismiss them as a gimmick. The word gimmick has a bad connotation as something that tricks, deceives, or confuses. Something that grabs attention but doesn't do what it claims to do.
In my opinion, the G2 RIP does what it claims to do:
(9mm - from their website)
- 14″– 16″ of Penetration
- 2″ Groupings at 25 yrds
- 9 Separate Wound Channels
- Solid Copper / Lead Free
- up to 6″ Diameter Spread
- Precision Machined
- Defeats all known barriers such as sheet metal, sheet rock, windshields, plywood, heavy winter clothing.
Ok, the last one is a stretch, depending on their definition of "defeat."
But look at luckygunner's gel test:
https://www.luckygunner.com/9mm-luger-g2-research-rip-92gr-hp-20#geltest
It appears that have substantiated their terminal performance claims. It confirms the penetration depth and diameter spread.
Then, the other extreme - Is it effective?
Again, not trying to be harsh here - but as another poster wrote - self inflicted, point blank, still alive.
From the gel test, most of the damage occurs between 2-6", with the leftover disc base going approx 14".
This thing isn't going to be adopted by the FBI, but the fragmentation appears uniform and repeatable.
However, the performance is not what
most CCW holders desire in a carry ammo. Sure, accuracy matters and the "shot placement above all else" squad exists, but so does expansion, penetration, and how the energy is expended. Frangible ammos by nature give up penetration for extreme expansion and a large, shallow energy dump with shrapnel. Without being a total regurgitating tool, a federal agency suggests 12-18" of penetration in 10% ballistic ordinance gelatin. The RIP meets this depth with the leftover frisbee-looking base of the bullet with a maximum .355" hole that travels another 6-8" after the petals stop at the 6" mark.
As PH would say, "You be the judge."
