so I'm at the range today with a few of my revolvers and I'm firing my single seven and out of the blue after firing a round I go to pull the hammer back to re cock for the next round and it wont pull back all the way . so I noticed the cylinder base pin is part way out, I pushed it back in and fired the rest of the rounds in the cylinder without issue . so next time I go to shoot it it does the same thing again , it ended up doing it several times while finishing up the box of ammo I was shooting . I wasn't shooting anything warm out of it just a powder coated lee 90 gr swc bullet over 4.2 gr of green dot . I did pull the pin to make sure there wasn't any crud anywhere causing it not to latch and found nothing . I later ran a whole box of 50 rcbs 98 wad cutters in 32 h&r cases through it with just a mild charge of 2.2 gr of bullseye and the pin never came out . i currently own 2 ruger black hawks and have owned other ruger single actions over the years and have never had this issue in the past , but from what I'm reading on line its pretty common . i plan to call ruger on Monday and see if they'll send me a new pin but I'm wondering if the latch assembly should be replaced also ? if so i have no idea how to get the old one out .
