I guess we're back to trying to figure out who is actually getting issued the weapon. "Standard" Mark 1 Marines or "special" Marines (no, not the short bus kind).
Somewhat off-topic... A few months ago I decided I'd shoot my almost completely stock 1911 in the monthly, friendly local match. This is after primarily shooting my 229. The first time I drew and squeezed nothing happened. Apparently the 1911 has some sort of "safety" the operator needs to push down on. Talk about muscle memory and needing to put more rounds down range. I plan to bring the 1911 to the match this Saturday, hopefully without the same results.
