COP 357. With 4 barrels you would get to shots. And only 2. Not always the same 2. It did make a good flinch detector. Owned for 2 years but the USPS had it in their possession more than I did. Constant trips back to the company that hired dyslexic chimps with ADHD to assemble the guns. Never did get it to work right. Finally took a hacksaw to it. I wasn't going to sell it to someone else.
