Bottom Line buy whatever you gotta buy so you can play (be safe
and have fun
). In my opinion you're far better off saving up for a better gun, it will give you much more value for your money in the long run (and the short run for that matter). It is after all a secondary weapon and not totally necessary better to save up.... ahh but you're 16 and don't quite realize the value of the long run yet. Don't get me wrong I'm not trying to rag on you just impress upon you that you're still a green tree and don't know it all yet.
It's a huge wast of time to come on ASC ask everyone what they think then totally ignore the advice you're given and come back only to say "hey look I bought 2". When you ask for advice sometimes you're going to hear what you don't want to hear. If buying the Walmart gun is your only option and/or is what you're going to do anyways don't bother asking, don't waste everyone's time.
Good luck with your deagles
