question about 1911

yesterday i was at the range working with a lady and her husband was 3 lanes down from us(2 inbetween) this was an indoor range with dividers between each range.

Her husband was firing a 1911--and we were being showered with brass. I watched him for a minute and he was breaking his wrist a little bit with the recoil--I did offer the suggestion that he tighten up his wrist a little.

So my question--is the 1911 prone to throwing brass (more than say my glock) or was it just something in his techniques?

thanks
