My new SR1911 came with a 7 round and an 8 round magazine. The 8 round magazine won't keep the slide open after the last round is fired. I've filled it and fired it until empty 5 times and each time the same results. Maybe a weak spring?

I did That and have had no issues in over a year. I also use the Chip McCormick shooting star mags and they work every time.
