>>63817266 (OP)Hello anon, it's me with the P90 from that picture. I bought it back in 2018 and SBR'ed it in 2023. I quite enjoy my P90 and it as well as my SP5 are the two guns in my collection that I have the most fun with. Nothing can match the small form factor, lightness and capacity and 5.7 is a really cool round. The ambi design and bottom eject are really nifty and the gun is all flash and noise and no recoil. Everyone always wants to fondle it and shoot it every time I go shooting and with FN ammo it's 100% reliable. It's just a super cool gun. I hope to fucking god we get an FRT soon and I'd unironically be willing to pay a grand for one if it works reliably.
The bad? The trigger kinda sucks but it's light for a bullpup. Reloads are a bit janky. It takes time to learn that safety albeit it's pretty good once you know what direction is what. There's no real good options for slings and the sling setup I have in your picture forces me to carry it across my chest or have it at my side or against my back and have the muzzle flip horizontally and sweep anyone to my side if I start running. Mounting an optic is going to be a headache and every option will have significant tradeoffs. I think the Ring Sight is the slickest option but the glass is kinda dark and the reticle suboptimal for really precise shooting. Zeroing the thing was a real nightmare too. You pretty much are going to have to SBR the thing because the 16" barrel is super lame and messes with the balance of the gun and drilling the pin out of the stupid shroud and then swapping the barrel out is certainly an experience. American Eagle and Fiocchi ammo will infrequently cause stoppages because they're pathetically weak loaded and because 5.7 has such a tiny powder charge any variance can cause cycling issues.
I do not regret my purchase and I've had it sitting beside my bed before for a home defense gun. I regularly take it on woods walks because of how compact and handy it is and I like it
