We try and keep our stage designs "1911 neutral". That is to say, you would fire a maximum of eight rounds and then do something like a few step movement to the next shooting position or a mandatory reload in the same box.
Yes, our club does have high round count stages (24, 28 even up to 32) but it sure is a lot of fun! We also have a few "stand and blast" stages of only eight rounds thrown in to balance out the match.
In direct answer to your question, bring anything that you want and have fun!
The post from Mikey shown above is the current hot ticket, STI or SV gun in .40 seems to be the ticket in Limited.
"...What will you do without freedom? Will you fight?... Fight, and you may die, run and you'll live, at least a while. And dying, many years from now, would you be willing to trade all the days from this day to that, for just one chance, one chance, to tell our enemies, that they may take our lives, but they'll never take our FREEDOM!!!"
