Yes, it is difficult to pull the hammer back, probably impossible for young nerfers. I also suspect it might be near the stress limit for the plastic hammer and trigger. For comparison, the BlasterParts Metal Hammershot kit has a 9kg spring.

I think LT is probably correct, it would be nearly impossible for people of average strength to prime a 14kg hammer with one hand. However, because of the design of the hammer/trigger interlock, it isn't necessary to have a stronger trigger spring. But having fired this Hammershot a few dozen times, I won't be surprised if the plastic trigger mech wears out before long. I searched a 14kg spring for the Hammershot & it shows up Longshot springs. I guess a 14kg Hammershot spring doesn't actually exist. xD
