As with any machine, some run 100%, some are a mechanical piece of shit.
Many on this board have had good results with theirs. Mine has been horrible.
It may be the throat but it'll reliable fail to feed after about 5 rounds and requires a thorough cleaning to make it function again. I Wolff heavy spring helps some but by only a round or two. Also, the rearmost trigger group pin has left a permanent scar on my thumb knuckle (the thumb joint closest to the webbing of your hand). I pushed the pin to the right which helped some but the edges of the frame where it pin goes still cuts me every time (circled in
RED).
I could send it in to Ruger and maybe they'll fix the loading issue, but there is nothing they can do about the frame cutting my thumb. So, why do I still have and carry it? I have sciatica and other lower back problems so carrying anything larger IWB is painful. I'd get something new in a heartbeat but to date, I haven't found anything better size wise. I had a Shield but even that I needed to carry OWB.
