DefenseReview’s (DR) been following and covering Maxim Defense products for awhile now (see “Related Articles” section below), so we’re always glad to see new products get introduced by the company. The latest the Maxim Defense MD-9 (also written MD9) 9mm Parabellum/9x19mm NATO weapons series, comprised of the MD9:905CS with Maxim CQB stock telescoping/collapsible buttstock, MD9:905CP with Maxim CQB brace arm brace, and MD9:905CPS with Maxim CQB pistol system (buffer tube).

Barrel length is 5.8″ (5.8 inches) to optimize performance/velocity with 124gr FMJ (Full Metal Jacket) ammo, so you’ll need a Form 4 for the MD9:905CS SBR (Short Barreled Rifle) variant. Speaking of this variant (DR’s personal favorite), here’s the company’s literature on it from their website:

“MD9:905CS
