Hi Jim, my first owned Pietta Paterson was purchased 1/2017. It has a date code of CN (2015). My second owned Pietta Paterson was purchased 8/2018. It has a date code of CS (2017). The serial numbers are only 100 apart. One can understand the lack of current production, minimal demand.

Regards,
Richard

Hi, I measured the arbor and barrel arbor hole for my two Pietta Patersons:

CN (2015) arbor = 0.430". barrel arbor hole = 0.434", difference = 0.004"
CS (2017) arbor = 0.433". barrel arbor hole = 0.440", difference = 0.007"

Look at the barrel end of the Paterson and see that there is a reduced section next to the arbor hole to allow wedging the barrel off the arbor. This seems to show that fouling is inherent with the Paterson design.

Regards,
Richard

Hi, Richard, does the single set screw function as both a barrel wedge adjustment and an arbor length adjustment?

Hi Kirk, the set screw just is used to adjust arbor length. A 10-32 screw would provide too small a surface area for a wedge adjustment. A small area would batter the wedge. Also, I don't drill the set screw hole all the way through the end of the arbor. If it was drilled all the way though it would weaken the part of the arbor that has to take the pressure load on firing.

Regards,
Richard

Hi, I came across a write up on the Paterson where fouling is discussed:

https://www.guns.com/news/review/colt-paterson-reproduction-by-pietta-is-a-worthwhile-experience

He found two things that can be done to reduce fouling. One is to increase the barrel/cylinder gap to the width of a playing card, (~0.011").  I had already discovered that a large Paterson gap is helpful to reduce fouling. The other is to use a non stick cooking spray on the arbor. Maybe something like PAM? I'll try PAM the next time shooting the Paterson and report back.

Richard

No reason PAM shouldn't work.

PAM works fine - for about 18 shots, then it's gone.

Three words:  White Lithium Grease. 

Put it on Sunday morning and shoot all week.

Hi G Dog, I already tried that, Lubriplate:
