WE M9 or Hi-Capa?

[Taho]

So, here's the deal. I have in my possession a WE M9 GBB as well as a WE Hi-Capa 5.1. I know, I know, eww. But getting to the point, I'd like to have a sidearm, and both of these guns need repairs. Would anyone happen to know if it would be best to invest in parts for the Hi-Capa, or the M9? And what parts could I get to make either more gas efficient? Thanks in advance to any responses.

My opinion is to sell them both and buy a KWA, KJW or higher quality gun. Because adding upgrades doesn't add any value to a WE gun. And you more than likely won't have to fix a KWA.

I'd absolutely love to get rid of them, but I don't think I know of anyone who will buy them for more than $20. That was my original plan, to sell them and get a KJW or KWA, but like I said I don't think I could sell them for more than $45 each. They're both pretty junk. The M9 needs a new mag, safety, and slide catch, and the Hi-Capa needs a new mag and safety.
