I have a KGP-141 .357, the only problem that I have is finding stuff to feed it.
.357 and even .38 special or +P ammo is next to impossible to find down where I live. Hopefully you have a good supply in your neck of the woods, or allready on hand.
Demand for ammo in this country is at unprecedented levels. The manufacturers are gearing up to start going 24/7 to meet it. We will start to see this soon. It takes time for them to get raw materials and labor to do it. This industry will boon and create jobs in many sectors.
