About
What it is, and why it matters
The PTR 9KT is PTR Industries' MP5K-pattern compact pistol, the shortest configuration in its 9mm roller-delayed blowback lineup. With a 5.83-inch suppressor-ready barrel threaded both 3-lug and 1/2x28, a 13.38-inch overall length and a stamped-steel receiver, it recreates the iconic machine-pistol-sized HK MP5K as a US-legal pistol. It includes a tungsten-weighted full-auto bolt carrier, Picatinny optics rail and M-LOK handguard, shipping with two magazines, adjustment tool, sling and cable lock in a foam-lined case.
MSRP approximately $1,889-$1,989. SKU PTR-603. Sold also as 9KT BR (folding brace), 9KT SBR SF (folding stock SBR), 9KT Pro Kit and 9KT Max Kit. Barrel threaded 3-lug and 1/2x28. Trigger pull 9-10 lbs.
