    Just bought my 2nd Pietta 1858 short barrel. My older one shoots great and I wanted the smaller one to handle my krist Konverter (thats how Krist spells it.). Put the Krist in and noticed that when I pulled back the hammer (unloaded) the bolt ( cylinder lock) dropped instead of snapping up and locking. Put a spare black powder cylinder did the same thing. Not only that but the cylinder turned backwards each tim a pulled the hammer back.

    So, I dropped the trigger guard on my older 1858 and the new one. The trigger bolt springs are different. New gun spring is longer. Put the older spring in and it didn't work at all. So I pulled out the bolt on both guns and what do ya know but the elves in Italy have been twitching the guts.

    The new bolt is thicker by a hair and the Cylider bolt cut out is wider. The bolt was not locking up into the older cylinder. Now if you have an older Pietta 1858 watch the springs. If you want to use an the older cylinder in the new gun, DO NOT TRY TO ENLARGE THE CUTOUTS. Instead get a new bolt and thin it down to fit the older cut out that will work. Remember a thinner bolt will not lock up the newer cylinder.

    If you order new guts for any Pietta, remember that there are some differences. I f I'm going to shoot the "Converter" I'll change out the bolt. Or make sure if you order any "spare cylinders" you get the right one. My older serial number starts out with R 33XXXX the new model starts with R 43XXX.

    Last thing, I didn't like the lock up on the new model, so I took a small washer, filled of the edges and placed it on top of the spring, put the screw back in and the gun locks better than it did yesterday when I bought.
