Maxim Defense is putting out one hit after another these days.  I recently reviewed the Maxim PDX Pistol in 7.62×39 and now here’s a look at their MKIV-SD Ruger suppressed pistol.  The MKIV-SD is a beautifully engineered piece of work.  Maxim has a line of suppressors for an array of calibers, but the MKIV-SD.  While there are many manufacturers producing stand-alone suppressors, this version was designed to be integrally suppressed specifically for the Ruger MKIV.

Maxim Defense press release:

The new Maxim Defense MKIV-SD is an Integral Suppressed Ruger MKIV Pistol. Choosing the finest modern .22LR pistol in the world, the integrated MKIV-SD suppressor is the quietest, purpose-built suppressor in category with the easiest maintainability.

The Ruger MKIV pistol, from which Maxim models this gun, is a legend in reliability. The MKIV was first produced in 1949; and Sturm, Ruger, and Co. have never looked back.

THE SUPPRESSOR

The MSX suppressor line by Maxim Defense is specifically designed to minimize the increase in cyclic rate and gas blowback of a suppressed weapon system.  Primary design features include the significant reduction of sound signature, decreasing flash signature, reduction of recoil, and increase in accuracy.  The integrated MKIV-SD suppressor is the quietest, purpose-built suppressor in category with the easiest maintainability.

Maxim’s state-of-the-art MonoKore suppressor is a simple, 3-piece design constructed using military grade materials.  The MonoKore design has been integrated into the Ruger MKIV pistol and uses integrated carbon cutters for cleaning the suppressor tube.  It features a secondary retention mechanism on the suppressor tube, adding 5.4” to the muzzle length.

THE VERDICT

A definite Yes!  The MKIV-SD is a winner!  By the way, do you know what the SD stands for?  Of course, you do!  It stands for suppressed, right?  It does in a way.  The SD stands for Schalldämpfer, which is German for Suppressor.  Just a bit of trivia for you to impress your shooting buddies.

That’s all for now folks!   Please keep sending in your questions, tips, and article ideas.  And as always – “Let’s Be Careful Out There”
