S&W MP40 green gas blowback pistol?

[Reaver_RRTS]

Hey guys...

Buddy o' mine I got into airsoft wants to pick this thing up from a local store. I can't seem to find much info on it since most are pulling up either CO2 versions or NBB versions, yet he says its a green gas compatible magazine with blowback action. On account of it's price (very cheap I must admit..) I'm wondering if anyone knows anything about this pistol, as he seems heartset on buying it. I don't have much against it, but since I bought my PX4 from the same place and the spring actuating the trigger broke before I could even actually use it, I'm wary.

Information would be greatly appreciated.

its either a KWC or a WA.

WA was the first to make then, they "WESTERN ARMS" on the slide

KWC is a clone of WA, most parts are interchangeable, KWC version MAY have the "SMITH AND WESSON" trademarks on it.

they are pretty reliable handguns,

sorry forgot to put its by KWC XD I don't know why i put S&W instead. Hmm... how's replacement parts for it?

If it's a KWC, say goodbye to replacements... unless things changed since I checked for my (now sold) KWC P226 X5
