Again, thanks for your input. And no, they are not Lorcins! I do have a Jennings in hard chrome however. Actually, the guns I was referring to were a Browning Hi Power and a CZ 85 Combat. Very nice guns both.
MR. G.,
Don't be afraid to shoot them. I heard all this stuff about Nickel finishes getting trashed on this board also hence my concern. However, if you look at the posts above, there is no reason to worry. I have used Shooters Choice and Hoppes for years. I guess I did it right. Finish is still there. Just wipe them down good and oil them a little.
I have one of the last production runs of the Electroless Nickel Browning Hi Powers. I got it around 86 or 87. I have shot it quite a bit. I used Shooters Choice and Hoppes #9 to clean the bore. I always wiped any excess off the Nickel finish.
See what Ledbetter. Peter and Mike said above. It holds true for me as well. I just got freaked because you hear these horror stories sometimes. It would appear with CLP and EEZOX, that there would be no worries at all.
I also have an 1855 Colt Side Hammer revolver in Nickel. I don't know how it was cleaned over the years but the Nickel is still almost all there. A few patches but nothing major. This is a real antique and I don't shoot it but it goes to show that Nickel is a durable finish.
