Actually it was never intended for pistol. It was designed for the FN p 90 to REPLACE the pistol because the troops can't hit shit with a hand gun.
Like with the BAR/ M-14 they keep trying the same failed ideas over and over.

Actually, 5.7×28mm ammo was ALWAYS intended for use in a pistol. FN 5.7×28mm ammunition was designed in conjunction with the FN P90 PDW and the FN Five-seveN pistol. "The FN 5.7×28mm (designated as the 5.7 × 28 by the C.I.P. is a small-caliber, high-velocity, smokeless powder, rebated rim, bottlenecked centerfire cartridge designed for handgun and personal defense weapon (PDW) uses and manufactured by FN Herstal."* BTW, the barrel of the P90 is only 0.8" longer than this pistol. With muzzle energy in excess of 9x19mm it does lots of things better than .22 LR and is far from useless.

Was looking for the NATO PDW RFP from the 80's but frankly lost interest after 10 minutes.

I would love to get one of the KelTec's but
1. For my use it really has no practical use.
2. It too large for everyday carry.
3. I don't have an extra $1K laying around.

I have a P-91 (Or 90, whichever is the semi-auto) and it is a LOT of fun to shoot even though the ammo is sky-high. Even more so during these trying times.
The time for action is upon us and the enemy is at our gates. Let us not allow them one more inch of advancement but instead throw them through the gates of Hell.

Don't feel bad.
Unless you were an half trained NATO conscript in the 70's - 80's, no one had a real use for it.
It was designed as a PDW for rear echelon, non shooting, types who might have run into Soviet Spetznaz if WW III broke out.
Apparently it was cheaper than actually training their troops.
7.62 x 25 works just as well.

But not as fun. You have to add "cool" factor into the mix!

Yeah really.  The P90 was a Stargate prop....

OK. You guys are better at this than I am.

I have heard (probably a rumor) of reloaders pulling the bullets out of the SS109  5.56 rounds and putting them in the 5.7x28 to increase penetration trying to get them close to the "outlawed" armor-piercing cartridge.

1. Do any of you know someone that has done this?
2. Does it come anywhere close to the desired result?

I am sure they are trying to achieve a round that would penetrate a "bullet-resistant" vest.

 ;D ;D :o :o :o :o

Looking at published load data, it looks like the heaviest bullet I could find listed was a .224 diameter 45 grain spitzer, So I would say that anything heavier and longer probably wouldn't work except as a single shot.

Do some LOA measurements.
Spitzer bullets in pistols are just stupid.

Doess any one other than me realize these ideas were thrown out as useless foolishness 120 years ago ?
By the late 1800's calibers below 7 MM had been rejected as useless by everyone but the Japanese, and THEY were disappointed in it's effect on Russians.
And THAT was with full rifle cartridges.

Stick, "NEW" or "Improved" on it and some dumb ass is sure to buy it.

If HK marketed a STANAG buttplug some of you would get one and hype it's advantages.
5.7 that you are wetting yourself over is nothing but FN trying to recover wasted research money.
