I would give a Palmer an even tighter inspectiuon than I would give a Monson, but if it passed I would view it as OK. The Palmers were viewed as just being a little looser in quality control of the fit & finish.
For those who may have an interest, I know of a stainless, six inch, full length under lug shroud, in 41 magnum that's up for sale at an emprorium about 30 miles from here.
I'd be interested, but given that I have a Dan Wesson, a S&W, a Colt, a Taurus, and a Super Blackhawk in 44 magnum and a S&W in 41 Magnum, it would be hard to persaude my wife of my desperate need for it.
