Springfield Armory's Kuna is a 9mm roller-delayed PDW design, now paired with an integrated Tri-Lug suppressor-mounting system, allowing compatible suppressors to be installed and removed without tools, using a push-and-twist connection. I don’t have a Kuna, but I have the tri-lug system on a few similar guns and it works great.

Springfield Armory Kuna @ TFB:

The upper receiver is monolithic aluminum, as usual, nothing has changed there, and the design keeps its full ambidextrousness and ships with two 30-round magazines. Two primary configurations are offered, one with a bare Picatinny rail at the rear of the receiver, and one with a side-folding Strike Industries FSA brace mounted.

Both tri-luggers are also available as low-capacity variants with 10-round magazines for areas with capacity restrictions. Springfield includes a FIRSTLINE program option offering discounts to qualified professionals.

Does the shift to Tri-Lug mounting change your approach to your suppressor inventory? Or do you prefer the normal factory 1/2×28 threaded barrel? I have both attachment systems on other 9mm PDWs, and if I were to answer the question, I couldn’t really tell if I have a preference. Both work a lot better than most (or all) Quick-Detach systems, especially once they get used and dirty.

    Did they ever fix the issue with casings getting stuck along the trigger group area?
