sorry about the dead guy and that you have to be the one found him/her.
back to the topic, we have all been there. based on you said, it seems we were similar at where to start, with the exception that I don't see these guns as investment. In fact, unless you are buying them to collect, like python etc, you will lose money one way or the other on the shooter guns, unless you got an extremely good deal for whatever reasons, either on sale or, like right now the currency fluctuates a lot. So, don't worry about that too much.
I don't have experience with Girsan, so do your research and go for it if you like it.
One thing to considered though, anything new would be harder to find accessories and after market parts, or with a more expensive price tag. With popular brands like S&W, Glock and general 1911s, it's very easy or relatively cheap to get those which is kind of important. this is one of the reasons lots of people, myself included, started with a range kit that gives you everything you need. just an example, in my city, Girsan 9mm is around $450 with 2 mags only. MP40/9mm range kit is $650(on sale will be between $550-600 now, saw $500 before the CAD went into toilet), but it comes with 1 extra mag($40 for MP9, $44 for MP40), mag loader($40), holster and mag pouch($50?) and different size of grips(not available for Girsan I think). So, the range kit from S&W is actually better value than Giran, all considered. and with MP40, you get a conversion barrel with 2 mags for $300 extra. you get two guns average @ around $450 each. So... how's that for a math?
sorry this is my views as of right this second im still eyeing up the originals too. just swaying back and forth. you guys are my soapbox a bit lol. well at least until this thread gets locked or i feel shy asking for opinions.
