ruger mark 1 failure to eject, weak ammo ?

[bcochran]

try a new recoil spring assembly. not an unusal problem. after 40 years experience with them, i variously replace the recoil spring assembly, clean thoroughly, change the extractor and get better ammo. sometimes the bulk ammo (i was going to use the word "sucks") doesn't function well. i also take apart and clean the magazines.
