Craigt,
I thought I saw a smile!!
Sounds like a good start on the new parts!!
IMO, I would shoot at least 50 rounds of your carry ammo to make sure all is well,and I believe you have achieved close to that-wow 100 rounds in an outing is a bit more than I care to do in my pup shooting these days!! I am proud of you!!
As far as the Remington primer issue,they have been known to be a bit harder than other brands in the past-this may be the answer?
Sighted vs Sightless issue,I have not compared the Pup with this,but do own Seecamps,and it has not been an issue with them!!
The general consensus has been that the sights do no harm,and "may" help with a bit longer shot if needed..
But,as we know,the Pup is meant for "closer" use..
Thank you for the report!!
Brenden
