I have a P14-45 with a similar issue. I contacted Para Ordnance (Remington) and they told me it had a lifetime warranty and explained how to send it in to their repair services. Came back in a few weeks good as new.
I give my grandson a pistol when he turned 21. All the paperwork was done online as a gift by only my grandson and I. He had to acquire a HQL before we could begin the process but once we did the transfer on line, he got not disapproved 7 days later.
I looked and couldnt find it, but I seem to recall a thread that started around 2010 that stated 125 grain .357 caused spalding between the cylinder and barrel. I'm old and my memory isnt that good anymore so I might be wrong.
I was in Ohio in July. Tried to buy a Remington 700 at the Walmart there. They showed me the Walmart paperwork that says no gun sales to Maryland residents.
Thats the same thing I was thinking. I don't think that the local LEO wants to get involved in sending comformation letters to all C&R applicants and renewals.
