Speaking of Kel-Tec, they have currently suspended production of the Kel-Tec PMR-30 (of which they weren’t really producing a lot of guns anyway) due to keyholing issues with the gun. For those not familiar with the term, keyholing is what happens with the rate of twist in the barrel doesn’t stabilize the bullet in flight.
