The 5.7x28mm, suitable for defense?

[Zerodefect]

It was designed to replace the little HK MP5. And purposely designed to have less chance of collateral damage, but still penetrate a UN blue helmet. SS, security details, etc. etc.

That's right. It was intended primarily to replace other existing submachine guns or PDW's. But what has happened over the last 30 years is the AR-type derivatives have done that instead, whether in 9x19, .300BLK (for suppression), or 5.56. Submachine guns like the P90, uzi, MP5, M3, MP7, UMP, Vector, Scorpion, Mac-10 have all become relics. It could be said this process actually began with the Stg 44, but my main point is that the P90 introduced in 1990 is no longer relevant. I mean last year the Army bought 350 B&T APC9K's. I don't see that going very much farther. They have their niche, but in almost every other circumstance, a person is better equipped with a something that is basically an AR/M4 derivative.

The round can be lethal. See: https://www.dallasnews.com/opinion/...he-gun-nidal-hasan-used-to-kill-at-fort-hood/

Does that mean if you used it in SD or the new Ruger, it would be effective? Probably so - but we can drop into all the jello tests, forever. They are big guns and not the easiest for CCW.

However, at home and if you do have some recoil sensitive handicaps, it would work. We can now go into zombie, meth, biker attackers, etc. but to the core
question of protection for most scenarios - if you mean at home probably and you can't shoot something as benign as a standard striker 9mm, it would work.

Biker attackers ?

*gulp*

Have we concluded that the handgun in this round is reasonable for someone who has physical limitations and not going to use it for EDC?

Isn't that the OP question? The other topics are interesting but ...

Same reason as using the the bull pup. That's why my shootin' buddy's wife (in her mid 60s) has the PS90 as her home defense "long arm" instead of anything else with more felt recoil.

If the recoil is going to cause injury or irritate existing hand and wrist condition the 5.7 would be great. It recoils like a 22lr pistol.
But the muzzle blast is pretty intense.

Well yes that is question I asked. However the big issue that makes the round unsuitable for protection for those of low and fixed income(such as me) is the cost of the pistols and ammo. The very limited range and availability of ammo is also large factor against using this cartridge.

That pretty much leaves you with 9mm in a semi-auto pistol, or maybe a .380 ACP locked breech semi-auto pistol for reduced felt recoil.

The very limited range and availability of ammo is also large factor against using this cartridge.

Do you mean range of products (firearms) available or the effective range of the cartridge?

The firearms and ammo brands and types.
