Is the 5.7x28mm dying a slow death or do you guys think this round is just gaining speed ?
Do we expect more firearms in this caliber to come out !? Anyone know of any 5.7x28mm day sales for tomorrow 5/7/2024????? |

Judging by the number of guns being cranked out in this caliber I would say it's doing quite well.
Better than I ever expected it to. Certainly not dying on the vine. |

I've never used it myself but I see PSA is keeping it alive they even have an MP7 type thing that fires it kinda cool but I'm all in on 9mm PCC's I have a bunch of 9mm stocked and I reload it.

I still can’t make up my mind. I was all set to add some sort of large format, braced pistol, but the Internet can’t even agree on whether it’s the greatest thing since the 5.56, or if it’s just a overblown and expensive 22 magnum. I’ll stick to my current calibers until you guys figure it out.
I will say this, if the price comes down to 5.56 levels, or even better, 9 mm levels, I will definitely pick one up. But as long as it remains where it currently is, I’ll keep thinking about it. |

Someone needs to use some of that 6.8x51 hybrid case 80ksi secret sauce on 5.7x28 so we can get legit rifle speed out of a 5" barrel.

I think it’s gaining in popularity. Kel-tec, S&W, PSA and FN making pistols now. I think Ruger is too???
I think that Smith and Wesson pistol in 22magnum would be fun though. 30 round capacity and ammo is almost half of what 5.7 costs. |

And I don’t know how you can build a micro compact around the 5.7 cartridge. I don't have any problem with a long barrel carrying AIWB, in fact a longer gun can be more comfortable. The grip height/width on an M&P 5.7 is about the same as a G43x, and those are the critical dimensions for me. I'm still not 100% sold on its terminal performance, but holy shit does that gun shoot flat even compared to my full size compensated 9mm guns. I think something can be said for accuracy at speed and 22rnds in the mag vs 15 for the same grip length. |

Cool cartridge for sure but I dislike how the straight walled case relies on a polymer lubricant to ensure reliable feeding and extraction. Just seems like a tolerance stacking issue waiting to happen. That said, FN5.7 and PS90s seem to get great reviews for reliability and the PS90 magazine design wouldn't work without the straight cases in the first place so maybe that point is moot. The other major downside to the polymer lubricant is it can cause issues with reloading and since it's already an expensive cartridge that's a bummer.

Quote HistoryOriginally Posted By M4-AK: Is 5.7 adaptable to a Compact Pistol? Theoretically, sure. The problem is that it's velocity-dependent for terminal effect, more so than rounds like 9mm. So if you put it in a gun with a short barrel you're going to lose a lot of velocity and thus terminal effect. FWIW, I like it. I have a PSA Rock and an FN PS90, which I'm not going to SBR because I want the velocity you get from the longer barrel. Even with the 16" barrel it's extremely compact and with a red dot, stupid easy to do snap head shots at 50 yards. Ballistically it's closer to .22 Magnum than 5.56 NATO, but that's not a problem, IMO. It's not intended for use as an infantry rifle. For a short range PDW it should work fine, especially from 10"+ barrels. I can see a use for it in pistols for people with hand problems or who are very sensitive to recoil, as long as their hands are large enough to hold the pistol. The PSA Rock holds 23 rounds in a flush fit magazine which somewhat compensates for the lower power level. |

We have a pile of 5.7 ammo at work. Nothing to shoot it out of, so there it sits, collecting dust. I wish I could either give it away, or find something chambered in it that I could “test fire” repeatedly.
Last time I looked it was super expensive. What a waste!! 😔 |

The rifled length of the PS90 barrel is 14.8", so not too much shorter than the length with the permanently attached flash hider. In contrast, the P90 has 10.39" barrel. I'd be more inclined to SBR it if we could also have the giggle switch. |

It's a mid point evolution of the PDW and PDW cartridge.
They used to be full auto, pistol caliber SMGs that relied on bursts to be effective, but lacked range and armor penetration. Next, was the 5.7 and 4.6 that penetrated armor and reached further, but were still low powered, and relied on bursts to affect stops. Later, we started shortening intermediate cartridge rifles to get more power per round, and more stops per magazine, without the risk of full auto. Currently, peak PDW is something like a Honey Badger or SIG Rattler in 300 BLK. The advantage of the P90 is super compact height. The FiveseveN is a lightweight, service size pistol that can penetrate soft armor. It's a niche cartridge but not useless. |

It’s established.
What’s holding it back is the per round cost for range fodder and availability of proven defensive loads. It will never approached 9x19, .45ACP or .22LR in popularity but it’s not going away. |
