Does anyone here own or shoot one of these? I’ve put money down on one I’ve been eyeballing for two years.Ive got a good local source for mags and ammo and my stepson has a Ruger chambered the same.

Not sure I would without trying first.

I’ve had my hands on a P90 while I was in the service. I loved it but it’s a slightly different animal. I’ve got a pdw in 5.56…always wanted one of these. Most reviews of the civilian model are very positive.

My brother in law has one, I never used it at the range.
When he showed it to me, I immediately disliked the layout and loading!
How do you carry 3 extra mags in your chest rig?
I prefer my Tavor in a CQB situation.

I have shot one. I liked it, but think the size and weight is comparable to modern light-weight AR15’s. The kick is a little less than an AR, but neither are uncomfortable. Other than ammo weight (5.7 is lighter than a 9mm cartridge), you are compromising on 5.56 capabilities (same can be said for PCC’s).
The PS90’s sight sucked, and mounting options were expensive and limited, not to mention the price of a red dot. This also adds a LOT to the scope height.
As a side note, I also fired an older Steyr Aug variant and preferred the Aug if a bullpup is preferred. You are losing a lot of capability for the one pound difference in rifle weight and ammo weight savings. Less of a difference in the 16" Aug version.
It’s my understanding that the action was not modified from the military/police version, and therefore can be finicky with normal to higher powered ammo (oversimplification is that the bolt moves too fast for reliable cycling with the longer barrel). I think this is a reason why “civilian” FN 5.7 ammo is slightly less powerful than their military/police options. Rumor has it that many years ago some PS90 fanatics would use lead golf tape to add weight to the bolt, and one company that specialized in the 5.7 offered a tungsten part replacement for $$$ every so often to slow down bolt movement for reliable operation with diversified ammo.
The same company that offers the tungsten part has mentioned that the P90/PS90 plastic stock has a weak point that tends to crack if you are running a lot of rounds through it over time.
I’ll add, the barrel is comprised of an inner barrel and outer sleeve. Therefore barrel shortening gets complicated (if you are thinking of getting an SBR stamp for it in the future).
Personally, I would place this in a similar category to a quality M1 Carbine, but with increased capacity, lighter ammo weight, and performance against armor with certain loadings.

I’ve tested the Springfield “Hellion” bullpup and I loved it. It will be my next firearm purchased.

I’ve already got it and 4 50 round mags on layaway. I’ve found a source for a killer short barrel should I desire to go that route.
