Non-1911 options:
Glock, 13 + 1
XD and XD-m, 13 + 1
S&W M&P is 14 + 1 with extended magazine (10 + 1 with flush mag)
Fullsize 1911 options:
Para Ordnance, several variations. 14 up to 18 + 1 (with after market base pad)
STI 2011, 12 or 14 + 1, depending on magazine.
There are others, but I'm comfortable recommending any of these.
