It is hard to subjectively say what is easy or hard, but my FX Crown required more, and a less linear, cocking force than my AA S510 for example. I applied a little PTFE thickened silicone grease and it has smoothed out nicely with that and a little time, however it still seems to require more force to cock than some other lever-actuated airguns. This may be due in part to it just having a short lever.
What you should be looking for is contact. Is the probe-breech interaction stiff because the o-ring is nice and snug on the probe (good) or because the probe is misaligned with the breech (not so good)? Is the resistance you're feeling coming from the breech at all, or resistance from the toggle locking spring? Is there something in the action that could benefit from a little lubrication?
Keep in mind an overwhelming majority of manufacturers, across industries, use sub-optimal lubricants. Many use oil in an application which demands grease, and often they use lubricants incapable of effectively preventing wear between two materials at that level of load. *shrug* For airguns in most locations, a PTFE thickened silicone grease seems to be the best compromise of safe for O-rings and protects metal-on-metal and metal-on-plastic even at elevated loads.
