Hey there guys, I've recently bought an ICS CXP-16 L and ordered some mid cap mag's for it. When they arrived I tried putting them in the gun and the catch isn't holding them. Upon inspecting the mag's, they look exactly the same apart from being 1-2mm thinner than the standard one that come with it so they are too narrow for the catch to keep them in. Anyone know any mag's that will fit my gun at a reasonable price? (mid caps) Thanks in advance. Chris
