Geco Amunition in Beretta M9


May 19, 2011, 10:16 PM
I just got 500 rounds Geco 124 grain fmj from I've heard very positive things about it. However, I know it's a little hotter than US made stuff. Also, it has steel mixed into the bullet. Will these factors cause any excessive or accelerated wear on my Beretta M9? Thank you in advance.

Since the ammo that the military uses in the Beretta is hotter than the hinges of Hades and their pistols seem to be holding up OK, I wouldn't worry about the GECO being a bit warm.

Thanks bestseller, any other thoughts or experiences with this ammo would be appreciated :)

I've heard this is very good stuff as well. Enjoy shooting it up. I shoot the hotter 9mm nato through my glocks with no issues. The bimetal jacket is not a problem for any quality handgun.

Gecco is my favourite ammo as I find it on the accurate side.

Gecco is the same as RWS which IIRC it is Swiss 124 gr NATO loaded ammo. I love the RWS stuff. I have been shooting it for a year or two now. I find it at Walmart on sale at $10 a pop or I get it from Weapons World for about $200 per 1000.

It is good clean accurate ammo. The only issue is that some indoor ranges will not let you shoot it because of the bi-metal jacket. The Bi-metal jacket is coated so it will not wear the pistol more than other ammo.

Thanks for the replies everyone!

I've been using the GECO ammo for several months and I've never found it to be "hot". A lot of the US-made range ammo seems a little underpowered to me, so maybe that's why some think the GECO is hot.

Somewhere in my foggy memory, I remember reading (on another forum) a response from the manufacturer of GECO ammo concerning rumors that it was loaded to NATO pressures. The response was that it was loaded to pressure levels consistent with SAAMI standards for non plus P ammo.

After some searching, I located the information mentioned above:

Please note, this was posted in 2003 when RWS was the manufacturer of GECO. Today, RUAG Ammotec of Switzerland is the manufacturer of both GECO and RWS. Some changes may have been made since 2003.

Thanks Dogguy, Much appreciated!

The GECO ammo is a little bit lower grade than the RWS, but it is good stuff. I haven't looked at Walmart lately, are they carrying RWS again? I hope so!

Just an FYI:

Standard 9mm Pressure = 35,000 psi
9mm NATO Pressure = 36,500 psi
9mm +P Pressure = 38,000 psi

9mm NATO ammo has only 4.2% more pressure, so the felt increase in recoil is slight, when compared to the 10% increase from standard to +P. Hell, I can barely tell the difference between my 147gr and 147gr +P HST rounds, and NATO ammo is nearly indistinguishable from normal!

I've run 700+ rounds through my Walther P99 in IDPA with only like 1 ammo related malfunciton, (my chamber just would not accept one round for some reason). It does run clean and accuracy is fine.

I'll keep buying it as long as it's available.

I have shot quite a bit of Geco and NATO 9mm in my M9. No problems.

Dont know where I picked up this Geco case but its much smaller? Made it thru my press OK but I took it apart and didnt want to shoot it..

Probably because the small K on the headstamp means Kurz, or Short.

I think you have a .380 ACP case there.

That's not short; that's ridiculously short. Wow.

I have heard only good things about the 124gr Geco FMJ, with your picture being the exception! Most people say it shoots really clean and is reliable. I've got 500 headed my way, and I'll most likely order a 1k more if I like it; the price is too good to pass up.

EDIT: Good pickup CZF. I just noticed that after I typed this up.

Would a .380 ACP case have 9mm stamped on it?

May 25, 2011, 10:05 PM

LOL :)

It's not an American round, and I'm guessing they don't call it .380 ACP wherever it's manufactured, instead calling it 9mm Kurz.

May 25, 2011, 10:33 PM
Good to know, My 25 ACP is marked 6,35 browning..

That's .380 you've got there man. I hope you didn't buy it thinking you got 9mm luger.

The .380 is a 9mm bullet in a shorter case. 9x17 vs. 9x19. Know in Europe as 9mm K (Kurt or Kurts is German I believe for short), 9mm Corto Italian for short and so on. Might have the spelling wrong but you get the idea. Interesting story about a 9mm Beretta 92 9mm.
I had said 92 out to the range one day along with my Kel Tec .380. I was loading up mags and shooting. The Beretta was going boom, boom, pop??? The slide barely moved and the round that popped ejected the spent case. I had always heard the Beretta's open top design would damn near shoot anything. Well somehow I mixed a .380 in with a mag of 9mm and it feed, fired, and ejected it. impressed the mess out of me. And as far as 9mm goes their is 9x17 (.380), 9x19 (Makarov cartridge), 9x21, 9x23, 356TSW, and on and on. Not to mention the latest incarnation of the mid bore 9mm the .357 SIG. Not sure but I think the .38 super is th 9x21. And then their is the 9mm Largo, 9mm Styer, and I'm sure I'm not getting them all. Sure have played with the fast mid bores over the years though.
