You live in one of the worst places in the world if by ".45" you mean M1911 clone. No new M1911 clones are available and used pistols command high prices, even poor examples. Pistols manufactured prior to 10/21/98 and in state can be purchased through a dealer, or manufactured prior to 10/21/98 through a private sale.
S&W is introducing a stainless M1911 at the SHOT show in February but it's not available yet. You can get Curio & Relic M1911's if you have a C&R license, which with a few parts changes can be gussied up to look and act like the newer clones and can be made to cost just as much. They're the same size, shape, and weight - that's why they call 'em M1911 clones You can buy a refinished Sistema Colt for $299 or a refinished Hartford Colt for $399 with a C&R license if you simply must have an M1911 clone.
You can get the superb SIG P220 in MA, at very competitive prices, and the S&W 45's and Performance Center .45's are also available at competitive prices, if you want a good shooting .45 - great shooting in the case of the SIG and PC models.
But if you must have a NIB M1911 clone right now, move. Until the AG's "safety" rules get overturned, without a chamber loaded indicator you won't be seeing them here. I collect real USGI M1911A1's but also have a Sistema to introduce people to what shooting a USGI .45 was like without handling my collector pistols. Otherwise it's a SIG P220 all the way.
