    Hey Guys...

    I have this pair of F. LLI. Pietta 1863, .310 Caliber, 5 Shot, Remington Pocket Pistols, that from the factory had a problem with the depth the #10 nipples were set into the revolving cylinder.

    The nipples, were, inset into the cylinder too deeply, and when the pistols were fired, half the time, the hammer would not strike the caps with enough force to ignite the powder charge.

    It occured to me, after looking at and measuring the distances carefully, that the nipples were inset too deeply into the cylinders by about 1/32 of an inch.
    As a test, I backed the nipples out, away from the cylinders a little distance of approximately 1/32 of an inch, and VIOLA, all cylinders now fired reliably and consistantly.

    So... I toddled my lil butt down to home depot, and surveryed their small hardware section looking for some sort of item I could use as a spacer. I came across some very thin, and small, snipped #8 lock washers, in 30 packs, for $1.29, and I picked up a couple packs.

    I spread, the snipped washers open, with needle nosed pliers, fitted them over the end of the nipples, and pressure fitted them down onto the base of the nipple for a firm, and locking fit. I then threaded them back into the cylinder.

    The fit was a bit tight, and snug, but they did seat all the way down very nicely, sealing the chambers well, raising up all nipples, on all chambers, the needed 1/32 of an inch.

    It works BEAUTIFULLY, and is CHEAP AS HELL.

    I just thought I would pass that on, in case, any other Pietta owners out there may be having similar problems with their revolver(s), which apparently, Pietta is a bit nortorious for.

    It's not that they're seated too deeply it's because the cones aren't always uniform in length or circumference. Your idea works and it's a good one. Most people go to Treso nipples tho if they have problems with caps seating.

    So, what your telling me is that Pietta took all the time and trouble to machine the cylinders properly, and then, fitted them with inferior crap nipples...


    Figures, only an Itallian manufacturer would do that... ROFLMAO...

    Wouldn't have selected lock washers as shims myself due to the gap..........Hard spring steel not designe to "seal" anything.......

    I'd have opted for some copper/tin, or even SS, flat washers. The "other issue" is, having "spaced out" the nipples, does sufficient thread engagement remain to keep the nipple at home during firing. Since you didn't report otherwise, your solution works......At least sort term..... >MW
