I find Geo’s comments most interesting, particularly since the wood to metal fit on my Armi Sport Spencer in .56-.50 is remarkably good, especially for this era; I would call the fit excellent. Even my FFL dealer commented on this when the gun arrived. All fixtures and screws were very tight, and have remained so. I have found that the internal parts are well polished, unlike the case of many replicas. I did not see anything that required stoning or polishing.
I can not comment usefully on the matter of steel hardness, since I have not shot my gun enough for such problems to surface, if they will at all. I did notice that the lock was essentially devoid of lubrication
, save for a smear of grease behind part of the tumbler, so unusual wear of the lock action may be due to that factor. The lack of lubrication has been cited elsewhere on this forum, so it would appear that all owners of Armi Sport Spencers should dismount their locks and oil them, if they have not already done so. The entire action could do with a good lubrication, when the gun is new.
The Starr double action revolver, made by Pietta, is an interesting replica, and fundamentally well made and finished. But they do tend to have a very serious cycling problem
, despite the fact that a notable gunsmith reportedly assisted Pietta in working out the problem. I found that the problem was due to a slight fault in the position of the pawl, with respect to the ratchet face of the rear of the cylinder. In the correct design, the pawl should be close to vertical and parallel to the ratchet face, when engaging the latter. In the Pietta version, the horizontal distance between the pawl pivot point and the rear of the cylinder is greater than it should be, allowing the pawl to lean forward under the pressure of its spring. This, in turn, causes the top of the pawl to catch on the cylinder ratchet teeth as it attempts to rise during the operating cycle. The geometry would be very difficult to alter, but I found that the problem can be corrected easily by grinding and polishing a bevel on the top forward edge of the pawl, so that it will not catch on the ratchet teeth. My Starr now cycles flawlessly on both action settings.
I posted a more detailed description of the procedure on the SASS Wire a couple of years ago........
