G2 Research Recalls R.I.P. .45 ACP Ammunition

No product launch is completely flawless and G2 Research knows this now all too well. On December 3rd, they announced a recall of all of their .45 ACP ammunition manufactured from July 1st to November 30th.

Their statement:

We have received some comments that the current issue 45 RIP is not compatible with Glock and its unsupported chambers. Due to this, we have revised our design to solve this issue. If you have a Glock .45, please call 678-533-2033 Ext 4 or email us through our website for a free replacement of your ammo. Check the inside of your .45 RIP box for a date. Do not use July- Nov through a Glock. This does not affect any other caliber or handgun.

    I’m wondering what the hell they did differently within a 5 month span that could change the way this ammunition works in only 1 specific gun model. Wouldn’t you think if they were loading more powder or changed the overall length, it would exhibit malfunctions in other types of pistols?

    So did they blow up some Glocks? I can’t imagine what else the problem could be, given the specific reference to “unsupported chambers.”

  • Don Ward

    Couldn’t happen to a more deserving ammunition maker and this god-awful, overhyped gimmick of a product that gives gun owners a bad name.

      Have you shot it? I shot some a few weekends ago. It penetrated soft body armor along with my Winchester ranger T 230g. In my defense I didn’t purchase it myself like you I got the Gimmicky vibe. I only shot one mag out of my sig 1911. So I cant really speak for long term performance. I agree with you though. I was just wondering if you had any hands on time with it.

    Most pistols have the feeding ramp extending into the chamber. I don’t know what makes Glock so special.

    Who buys this crap?

  • The Real Teal’c

    Big chamber, tight bore. Works great with jacketed projectiles, but play with a monolithic copper projectile with an odd bearing surface and you have this.

  • I’m sure you meant to type “feed ramps”

  • 9mm Glocks, at least the Gen. 3s and 4s, have supported chambers. .40S&W and .45ACP, not so much. Not sure about .380ACP, .357Sig, and 10mm.

    Glock Perfection!

    Does this mean they actually sold some?

  • dan citizen

    Seriously, who does the R&D on a cartridge and doesn’t test it in a glock?

  • whamprod

    I hate that gimmicky stuff.

    But hey…. Don’t most 1911A1 pattern pistols also have unsupported chambers? Or is it only Glock owners who buy this stuff?
