Definately not normal.
Neutrik is perfect, even from the highest-end point of view. So called high-end manufacurers often use China clones with nicer casing and that's very often the problem, even with very expensive cables.
Neutrix FX/MX plugs need less force than Neutrik FXX/MXX.
Neutrik FXX/MXX and FX/MX have identical contact units but different casings. Both are perfect XLR plugs.
Always use Neutrik gold plated versions (contacts, pins), never use silver plated versions (severe corrosion over time).
From many, many tests I strongly recommend the Sommer Carbokab 225 XLR cables. Assembled by Sommer with Neutrik FX/MX (gold plated), different lenghts available (prices are per piece).
Also Carbokab 225 as a cinch cable if correctly assembled (pseudo balanced).
The Neutrik cinch plug NF2 CB-2 is also perfect, by far better than any WSS, Furutech, BulletPlugs or whatever. But they need a higher force to plug/unplug, so you have to act carefully.
May the force be...
