Product description
The CAA MCK Gen 1 conversion kit for the Sig Sauer P320 Full Size and Compact sets your P320 inside a lightweight chassis built from a polymer body and an aluminum barrel shroud.
This is CAA's original MCK design, and the concept is easy to follow. You don't take the pistol apart. Place the P320 in the kit, lock it, and go. When you take it back out, the pistol is in its original configuration.
You get plenty of mounting space. The top Picatinny rail lets you combine sights and optics, while side rails hold thumb rests, lights or lasers. A front holder keeps a spare magazine ready for a faster reload. The built-in charging handle speeds up assembly, handling is ambidextrous, and you keep direct access to the slide release.
One fit warning: CAA states this kit is not compatible with Wilson Combat frames, so check your frame before ordering. It comes in Black, FDE Tan, OD Green and Tungsten Grey, and CAA builds it in the USA. A few states restrict conversion kits, so verify your local rules; we don't ship to those states.
