I have a new to me PS-90. It's sidelined right now as I wait for a lower optics mounting solution  (HBI for the Slx1x). My intention is to file a Form 1 to convert to SBR, but want to shoot it first to make sure I'm happy with it.

The gun came with a small quantity of SS197, and I have a few of the SS198lf green tips left from my FN Fiveseven. I want to slowly build up a small ammo stockpile (after test fire) and I'd like to know what you all think is a superior choice for self defense type ammunition.

I was interested in the Speer Gold Dot and the Critical Defense offerings, but I see they are not recommended for the PS-90. Not interested in unobtainium SS190 or boutique ammo. Something that a PD might issue is my preference just for a modicum of legal protection.

So, what's your take on the best choice for working ammo?

SS198LF is a good choice.  Limited penetration.  70 cents/round here:
I bought some of this.  Haven't shot any yet.  
My own view is that left-wing positions largely come about from resentment, I agree with Nietzsche, a resentment about the surrounding social order. They have privileges, I don't. Or, I have them and I can't live up to them. Roger Scruton

For premium defensive use, Vanguard Outfitters' "Black Dragon Fang" 34gr lathe-turned copper solids.

For cost-effective and still decent defensive use, Fiocchi bulk-pack 40gr FMJ.

Or thereabouts in that order.


SS198LF has way too much limited penetration..

I just gel tested 4 types from a Ruger LC Charger.  Speer Gold Dot expanded the best, followed by SS197sr.  FN GUNR and American Eagle didn't really expand, just deformed a little

I heard the Spear GD isn’t recommended in the PS90

Correct. It lacks a case neck crimp. It also has an open nose profile, which makes it more prone to failure to feed and then because of that case lacking a crimp, bullet set back.

FN states in their owners manual to only use FN ammo on the PS90 fpr proper function

Except “FN” SS197 (Blue Tip) is really Fiocchi manufactured!

Speer Gold Dot 5.7 ammo is officially licensed 5.7 ammo and is covered in that statement, however Fiocchi's poor decision to not crimp the case neck and the more open tip of the gold dot means that if feed angle isn't perfect, there can be hangups :D

I have run a few non-FN brands of ammo through my PS90 and haven't had any problems, minus 1 round out of 600. It was from a box of Fiocchi 40 grain in the 150 round pack and the bullet recessed into the case but didn't feed. I checked all the other rounds and they seemed ok.  I have shot many Speer GD rounds through it without issue, in both PS90 and pistol. For range ammo they are fine but I also have some FN 197 if for some reason I need something serious but the little gun is for fun.
