I dug my old CO2 pellet pistols out of the garage - neither work. I contacted S&W to see if they offer any service and they said they’d get right back. Nothing further. I found long lists of people on the internet who supposedly offer repair service and I emailed about ten - no response also tried some phone numbers. Looks like One can buy a Sheridan repair kit but I’d prefer getting it done by someone who does that. Any ideas?
