I run C-product 20 rounders. I've found it has to run a milspect trigger weight to be reliable with steel case. I also use an H2 buffer.C-Products mags. Does anyone have real life personal experience with the different round count mags? Conclusions about what will hold what reliably, they all run about the same with some hiccups, etc?
Researching it seems all over the place. Other than 10rd which seem to run just fine for all.
