Be careful with the Uplula. I ditched mine after it dented some cases with the pressure of its finger. Of course I realize the issue may have been my technique. Anyway, mine with load to capacity with finger pressure. . .

This thread has been very helpful, but I have a couple of questions still.

I have 4 STI tubes with recently installed Dawson SNL's, STI springs and Dawson followers. One of the STI tubes was recently purchased new and the three others were used when I got them.

The newest tube will take 19 reloadable (RL) and 20 non-reloadable (NRL), but the three older mags will only take 18 RL and 19 NRL. I am using the spring that cam with the newest mag with is more compressed than the three STI replacement springs when out of the mag.

I have used these in 3 matches and they have been 100% reliable when loaded with 18, but would really like to get the capacity up at least ! more and hopefully 2 more.

What changes should/could I make?

Thanks,

Allen

I would purchase Grams spring/follower (11 coil for 140mm tubes) kit from here that should get you 20 re-loadable(mine are) if the tubes are right if not you will get 19. If you want reliable 20 reloadable send your mags here and have Bobby tune them.
