I just purchase a new Citori CX. I went to the range and had a conversation with someone there and he mentioned that if you use the gun allot it will last about 2 years. I'm a little skeptical of this claim. How long can I expect my new over and under to last? Thanks in advance.
Just keep the hinge / pivot clean and lubed; don't let any metal galling start. Take it down every couple hundred rounds and clean off / re-lube the pivot and engagement areas per owners manual. If you hear or feel any grit / grinding in the action strip it down and clean / lube immediately. Don't neglect the choke tubes / bbl threads. No different than any other O/U; built to last.
