Bug-

My favorite combos have all been old german sxs rimfire cape guns. I've owned five or six of them, two of them hammerless snap action with cocking indicators, the others snap action with hammers.
I have kept one through it all, my favorite (actually the most plain-jane of them all) 22rifle next to 9mmShot

It's squirrel brain accurate and absolutely silent with CCI CB long ammunition - hammer strike and impact slap are louder than muzzle report. I use it more than any of my other guns and rifles maintaining the integrity of my 30-year roof job.
At close range the 9mm side is quite effective on pigeons-on-the-wing.

Great little combo gun.
