I have the Pietta. 1873 in .357/.38sp, in .357 it is a chore to hold the grips and accuracy suffers, but with .38sp, it is a lot of fun to shoot and quite accurate!
I bought a couple of .357mag Pietta Millenium 1873 SA pistols from Marstar back in Dec. 2013 and have only put about 160 rounds of .357 through them so far. Accuracy is so-so, but it is a SA after all. However, I recently acquired a Laserlyte PRE and LASR software for dry fire practice. The Laserlyte PRE fits into the firearm barrel. When inserting/removing the Laserlyte into/out of the Pietta pistol barrels, I found that both pistols seemed to have a ridge at the barrel outlet ( one worse that the other). I surmise that this was caused when the crown was cut but it does make me wonder about the barrels metal treatment/QC. I would expect this to cause accuracy issues.
I'm exchanging emails with Marstar about it, so we'll see what comes of it. The Laserlyte PRE slides in/out of other firearms just fine.
