Sometimes, Zoom meetings just don't do a product justice. CAA's MCK (micro-conversion kit) has indeed been out for a while, but it wasn't until I got to finally see one up close that I understood just how much fun this handgun accessory promises, and what a boon it will be for NRA Women looking to get the most out of their range time. The MCK isn't a gun at all; it's actually a chassis that allows you to snap your handgun into it. When you do so, you now have a pistol that's sized and balanced in much the same way a rifle is ... but it's not a rifle, it's just a handgun that's (temporarily) been made a lot bigger.

When I say "snap your handgun in," I mean that fitting your pistol into the MCK chassis is literally a matter of sliding it home until you hear it click. Removing your pistol from the MCK is a matter of snapping it back out again. It's that easy. The real fun, however, lies in the fact that the MCK lets you shoot a beefy caliber through a tiny, lightweight concealed-carry pistol without crying "Uncle." In addition to near-zero hassle, there's near-zero recoil.

The MCK features a simple charging handle (much like the one in an AR-15) that allows you to ready your handgun to fire. The chassis is hinged, so you can easily fold it into a more compact arrangement for easy transport. There are nearly unlimited accessories that let you deck your MCK out, as well as a dizzying array of colors and finishes. Most impressive, however, is the number of handguns models with which the MCK is compatible: 250. 

“We do our research in-house to determine potential new models, but in all honesty, it’s our public, through our active social media sites, that lets us know what pistol is high on their ‘need to have MCK’ list,” LTC. (Ret.) Mikey Hartman, CEO of CAA USA, said. “When one of the major firearms companies hits a home run on a new pistol, like the SIG 365 or the Springfield Hellcat, you can be sure we will have numerous vocal fans asking for an MCK version.” 

Prices depend upon the model, and run $249-$449. CAAGearup.com
