Senor VoyPescado,
My esteemed colleague Sir Chas. brings up a good point. I have 2 different sets of TRESO nips and both work best
for me with Remington #11s.
It is my understanding that these nipples are made at or near and for "The Possibles Shop" in Roswell, New Mexico.
http://www.possibleshop.com/s-s-nipples.html For my 2nd set of nips, I couldn't find the right ones. This was for use on my 1860 Army Colt (repro) made in the early/mid 1970s by Uberti and by Iver Johnson, who was under contract with Colt to assemble and manufacture parts that became the 2nd Generation Colt C&B guns. Mine did NOT have the Uberti sized nips of today. When I talked to the fellow at the Possibles Shop - or the actual manufacturer they get them from, he had me send in the cylinder and he fit or made plieces that fit. When it came back, all was perfect.
And I think the guy
You spoke to is mistaken. From true experts (not sales folks) the word is that the hammer face should
just miss "kissing" the face of the cones (old term for nipples.) If the hammer keeps hitting them, they WILL mushroom the end of the cones and batter the face of the hammer. NOT GOOD, I say. .003"-.005" should be about the space needed between the face of the hammer and the tip of the nip.
By the way - my 1860 nips DID touch the hammer (before) I replaced the original nips with Uncle Mike's Stainless Steel nipples and now I have a nipple-sized indent on the face of the hammer. I have heard of splits and chips damage to the hammer as well as the nipple deformation and breakage because of contact between the parts.
If (as so many of these old repros are) the pistol is hardly ever fired, mis-fitted nipples/hammer face dimensions are likely no real problem, but if you are a competitor, you can put more use on one of these guns in a year than most get in a lifetime. Originals, too!
Have fun!!
