Gun has no leaks but fires slow, wont allow quick follow up shots like the piston is sticking. Any ideas? thanks

Could be really dry inside. Take cap off....look at the cylinder....might have o-ring build up in there. Clean - re-lube. If not, run an o-ring kit through it. Keep it well lubed. Help span the life a bit.

Freezing weather? Condensation from air might be building up. I found that WD40 helps.

You might have a bad bumper. same happened to me. these nail guns are thirsty so keep the oil to them.
