I've recently been CC'ing a Sig 226 Stainless Elite and like it a lot but it is a bit big and over your limit.
I've had good luck with a Sig P239 in 9, but it also comes in 357sig and 40. Small, smooth angles, lightweight, scary accurate.
But I've had my eye on a Sig 220 Compact 45. Beaver tail, Short Reset Trigger, Very Concealable.
Man, I've got to find the extra dough.
