I have a 39 Centennial with a 20" octagonal barrel that I put a Williams receiver sight on. It's one of my all time favorite rifles. Accurate and light and perfect trigger time for keeping my guide gun skills up.My favorite is my Marlin 1894c (.357, 18 1/2"), with the M 1894s (.44 with 20") a close second. I'm interested in 1897's, 39a's, etc. Can't decide which I'd prefer. I currently don't own any .22 cal. levers.
