SW1911 .45acp about $750 - $800 around Ma.
Great firearm, basic, reliable, comfortable to carry. Stock 3 dot sights and rubber grips, it is a work horse of a carry.
Absolutely love mine, around 2500 rounds down range, no issues or FTF. Favorite of all my firearms, hands down.
Use the rest of your budget for ammo and holsters.
Enjoy!!! IMHO the 1911 is a great platform!!
