I am looking to identify the 9mm JHP factory defense ammo with the longest overall length, closest to 1.15". I will buy some boxes of that ammo and verify, but I am hoping to save a little expense and narrow down the options a bit first. Any help on this is appreciated.

I believe 9mm Golden Saber generally are longer rounds, so I was going to check these out. What else?


Thanks.

I measured the following:
Hornady Critical Duty +P and standard was about 1.142.
Magtech 147 Bonded is 1.147.
Speer 147 G2 Gold Dot was 1.40.

Rem GS 124 Bonded went 1.132.

If you go FMJ, you can get 1.15 and beyond with several different 124 grain rounds.

Very helpful. Thanks! Just curious, was the critical duty OAL to the metal or the end of the insert?

Speed, what's the advantage of the longer ammo?

You beat me to the question - I was going to ask why OAL is important as long as the ammo runs in your gun(s) and has a record of performing adequately in gel and real-world shootings.

I certainly am not 2nd guessing Speed. I'm thinking outloud so to speak.
Colt 1911 9mm mags have a spacer to reduce back to front distance. In this example, it was thought that the mag had too much space. 9mm bullets do rattle in staggered high cap magazines, and I have observed that this event varies in degree from one pistol model to another. The Browning H.P. is the worst(my observation)in this regard. Perhaps a longer round would offend less, but I doubt it. It ocurs because the 9mm case is tapered. I've noticed that in some pistols, when a round is fired, the next one up has moved forward. My observation is that this event occurs more frequently in staggered 9mm mags. So after having said all this, I still can't think of an advantage of a longer round. Neither can I think of a disadvantage.

Exactly where I stand. I'm not against rounds on the longer end of the 9mm spectrum, but I'm not specifically for them either. To my mind, any JHP on Doc's list which reliably runs my guns is fine. OAL just isn't something that's a [direct] concern for me, and I'm curious to know why it is for somebody else.
