I did my part:
S&W M&P AR-15
S&W M&P AR-15-22
S&W M&P 357sig Compact
S&W 915
S&W .38 revolver (Police)
In a real life situation, once is too often, but even on the range, I couldn't get through two or three sessions of practice without jamming.
None of my revolvers ever jammed, I've had misfires {very rare} but that didn't prevent the next round from firing.
How do you like the S&W M&P AR-15-22? I think I want one.
