I just installed the Mag Guts into my 7 round magazine. That was one very squirrelly and very sharp spring! It took several tries but I got the lock plate and mag bottom on. Then I pulled the curved spring over the notch in the front.
I followed the Mag Guts' Youtube video's instructions.
However, I cannot get more than 7 rounds into the mag.
Is that normal? Would letting it sit overnight loosen it enough for the 8th round to go in?
