As above, the muzzle report is quite loud, but the noise from the cans being hit will be just as loud.

So, maybe, some quieter targets?

Also, you mention that you had been considering the pump-up? Maybe a good move as, even if you have issues, putting three pumps in is really easy and they're much, much quieter if you're not pumping to full power.

I have a 1377 and a couple of 2240s and like them all. And the pump-up will be cheaper to run, too.
