I guess I got lucky. My mags aren’t tuned, and they are the older ones were every mag is slightly different. Once I fitted the followers and base plates, they stay with that mag body. Also, I run Aftec extractors so finicky extractors is not a thing for me.
ETA: I have over 150K Through wide body 1911s. Last season I shot my SV open all season without cleaning. It was a light season, but easily over 6K.
