My dad bought one in .45ACP. I have it now, he's been gone over 15 years now.
I have had one malfunction out of many, many thousands of round fired.
A sliver of 'nickel' jammed the firing pin so the hammer couldn't cause it to move, froze up! The only place that sliver of nickel could have came from was from a plated casing. After I broke the weapon down and prodded the firing pin, the sliver fell out. That was a bunch of rounds ago.
I have replaced the buffer and springs. Runs like a champ.
For Police use, I could have used it but carried an AR-180 in the car before I got it and never changed. Good round but a little short ranged for my desires.
No, it is not for sale.
