Gents,
The real issue here is money. What is your budget?
If you have $1500+ to spend, buy the real deal. There is no reason not to. Do your research, make sure you don't get taken, and own a piece of history. Shoot it if you like. They are still available and you cannot get more mil-specky than the real deal.
$1000 will net you a Colt reproduction of the M1911 or reproduction M1911A1
if you can find one for sale. A grand will also net you a real M1911 with some issues to iron out. Your choice. Own a quality reproduction, or become the custodian of history. Either can be shot or simply fondled.
$500 is the Springfield GI45's territory. It has a slot in the barrel hood for a LCI. The MSH with ILS can be swapped out with a lanyard looped unit from Sarco for under $20. The thumb safety, slide stop, hammer and mag release can easily be swapped out with GI parts. Real GI triggers are still available from Numrich. Real GI Grips are also available for $10 or so. This was my choice. I bought a GI45 for $425 when they first came out, swapped parts, and came up with my own replica for under $500. Unfortunately, the very first GI45s had Springfield's old blocky front strap. I live with it. Some will dispute my wooden grips. The M1911A1s on my ship wore wood. Thus my copy wears wood. See my pic below.
$400 or so will get you a
Sistema. These are Colts, built in Argentina according to the 1927 blueprints. Lipseys just broght in the last of them, and they were not in very good condition. Expect to see them clearanced around $250. Rearsenaled sistemas in better condition fetch the $400 tag.
$300-400 is the range for the Auto-Ordnance, Kahr, and Rock Island Armory. I have not owned these pistols and I will not disparage them. Many people like theirs.
