I hope this is in the right forum. I have a Mowhawk 10c. I need a replacement clip for it. E-parts.com (Numrich / Gun parts.com) has them listed but are out of stock. I was told the nylon 66 and 77 take the same clip as mine. But the 5 shot clip is $3 more than the 10 shot. Is this supply & demand or is the 5 shot clip metal? I have a 10 shot now but it's plastic and it's marked mod.77.
