berger: Very strong and safe rifles- for black powder. You should be OK if you buy one from a reputable seller who is willing to state that it appears mechanically very good. My 3 vary from a mint condition Mk I with all matching original parts to a recent purchase of an "untouched" Mk II from IMA- all very shootable. The worst problems on the latter were patches of pitting on the outside of the barrel at the woodline but not deep enough to worry about. Surprisingly, even Nepali Martinis tend to have very good bores. About the only thing a gunsmith could do is give it a close check for any cracks or obvious functionality issues and maybe, check headspace but even that requires knowledge given the type of brass generally used to shoot these. You could advertise for one that has been recently used although no private or commercial seller is going to certify it as "safe to shoot".
