Cleaning my other halves MP shield 380 ez today. Roll pin above the trigger has tried to escape its enclosure. Tucked it back in for now, but is this a common issue with roll pins?
I thought the engineering here is that a roll pin should never move. If this is the case then I think I need a springier pin. I’ll need to see if there are replacements out there. I have a lot of automotive tools, little in the way of punches. Just remedied that, so next time placing it should be easier.
Most roll pins can be “gently” persuaded to get a little “wider” with the use of a tapered finishing nail. It takes a little time with a file and a drill to make but a couple gentle taps with a light hammer is all that is needed to expand the roll pin. Getting the finish nail out is usually more difficult than expanding the roll pin. Hint add LUBE. With poly framed guns it is very easy to “wallow” out your frame hole with a pin punch or some other tool making it not so secure for the roll pin. I have no experience with the M&P this is roll pin knowledge only.
