It depends on what you mean by normal... Every Swisstool I've tried has a loose plier pivot with lateral play. That's four Spirits (2 RTs, an S and an X), and a regular Swisstool X. All of them had play in the pliers.
I sent one RT in to Victorinox with a detailed notation of the plier's problem. It came back two months later completely untouched. Play was still there, a question mark was written on the packing slip, and that was pretty much it.
Normal? Maybe not, but not uncommon at all. Your best best is as mentioned above, fix it yourself.
