Atlantic Firearms had the KUSA KP9 marked down to $795 so I had to pick one up. They appear to still be in stock if anyone is interested. Also, I added a x2 magazine pack to the order and it discounted that to $35 so I got that too.

I plan to SBR this so I put the KUSA triangle folder on order.

What do I need to check out on this pistol before I apply for a stamp? Just general inspection/function or are there some significant trouble areas to look at?

Thanks!

I've also done one and haven't had any issues. I'd just make sure that the gun functions well, and that you can get the stock retaining pin out first, as I SBR'ed a PSA AK and then found out I couldn't get it out even with a sledge hammer.

Thanks for the tip. The video makes it look easy but I always end up being an exception . Would that be a deal breaker for you, or would you just accept defeat and find a professional to knock the pin out? I emailed KUSA to see if they would remove the pin for me if I have trouble.

I would look to make sure it has a round bevelled firing pin.  If it has a flat pin, it can fire out of battery.  They fixed this with the new round and beveled firing pin.

I just got my kp9 yesterday and it does have the new firing pin.  I checked to see if I could get it to dimple a primer slightly OOB and it would not.

My KP-9 has been a beast, that’s all I got. Pull the trigger, goes bang, every time.

Fired mine today for the first time. Was surprised at just how easily it will shoulder bump.

Love mine. It's one of my favorite SBR's. I had no issues with my bolt but sent it back and received new one from KUSA last year. I installed a folding triangle stock with Russian adjustable cheek riser.

Hope KUSA opens up and begins making them again.  Closest thing to a Vityez out there.
