As many of you will no doubt recall, I’ve been very skeptical of ‘pistols’ based on military autoloading rifles. I’ve consigned several of them to the Deepest Depths Of Uselessness abyss and many of you have vigorously exercized your God-given right to disagree with me. Loudly. Primary Weapon Systems has just loaned us a very posh MK107 AR pistol for testing, and as I play with this $1900 specialty firearm, I can feel my curmudgeonly skepticism starting to erode. If I’m ever going to change my mind about MSR-based pistols, this Wylde-chambered piston gun will be what does it . . .
