Indians For Guns

Hi,
I am in the market to buy some airsoft products and i had some queries for that. My main need for airsoft weapons is for film shoots, so i need the weapons to look realistic.
Now, let me list what i know up until now, and if i am wrong,you guys can correct me and give me sage advice.
First and foremost , the guns i am looking for are-
1. Either a glock 17/glock 21, or Beretta PX4 Storm, or a Colt Defender or a Walther CP99. They have to have blowback action. and built to scale. I will also need a silencer that will go with it. Also, i will need extra magazines.
2. A glock 18/ 18c or Beretta M93R with the larger magazines. Again, full blowback action. Again, extra magazines needed.

3. Finally, I will need a H&K MP5 and/or M4A1 SOCOM rifle.

Now, i understand that the cheapest ones don't have any blowback action. I know Marushin has some really great handguns and even shotguns which even have shell casings ejecting during the firing action, but they are gas operated, not electrical. And shell casing ejection isnt that important, vfx can take care of that during the shoot.
I am guessing that the electrical ones are the most expensive. If they are built to scale and use a battery (A4 or other) to control the firing, then i will probably have to pay a premium price for them.
Now what i dont know about is the gas operated ones- so how much will buying gas cost me? Can i refill locally or would i have to buy a new canister/cylinder every single time??
Are there any dealers who has these products? I can settle for the the first 2, i dont even need the 3rd option right now. So can you guys suggest some shops and model numbers for me? I would prefer any shop where i can go check the product out myself over buying online- and in that case what kind of trouble can i come up with customs and the law? Online purchase would be the last resort. Also ,would online purchase be cheaper? I live in Calcutta, so local sellers would be more welcome. Many thanks in advance.

its been more than a month and a half and no one knows anything about this? I have checked local shops which might have had some but they are cheap and wont last more than a week. I dont mind spending money to get scale model replicas with actual action.

at least could anyone tell me about where to get co2 canisters cylinders? or what about websites that do send such products to india?
i have already checked 20north and ebay global buy, and both are proving to be useless. More importantly, what are the legal implications? Guys, please help me out, any info would be welcome.

Nomoshkar Lamatnes,

Dont mean to be impolite but I see that you havent posted an introduction yet. That's like barging in unannounced.

Please go ahead and post one in the Introduction and Welcomes section. That should help folks know who you are and what you're looking for.

As far as buying airsoft guns go, why dont you try to purchase Blank PFC guns. They should address your filming needs, blowback, cartridge ejection, and even the BANG no gas or battery power required.
Legality: Owning such a blank firer or PFC gun is legal as long as its not used to intimidate someone or used/posed as a real 'weapon' to commit a crime.

Most folks here are into airguns and firearms primarily, with little or no exposure to airsoft. Which might explain the stoic silence you encountered.

You might want to reach out to a couple of folks here who have details or might even have blankers on them if you are lucky, they are:
