J.P. Sauer Krupp Steel

[David]

I was at a small gunshow this weekend and picked up a J.P. Sauer drilling in 16ga. I'm not sure the rifle caliber yet but, will find out this week. This gun is in unbelievable condition. The breakdown lever is under the trigger gaurd. It has side plates and hammers. Flip up site on the rib. And also has a peep site on the back tang. I will try to post some pictures as soon as I can. Bores are shiny as new, rifle barrel looks like new. Has Krupp steel barrels. I want to take it rabbit hunting Wednesday. Do you guys think it would be safe to shoot? And, should I use 2 1/2 inch shells?
Thanks for any help,
David
