Since there already exists a similar design, why do the current standard-issue matchlock guns use firing rods instead of blocking pieces?
The reason is simple: firstly, when a rest is available, holding a gun with a couple more fingers doesn't make much of a difference; secondly, the lever structure of the gun mechanism would amplify resistance, making a small firing rod very hard to pull.
Considering actual battlefield conditions such as rust, poor lubrication, and foreign object blockage, using a tiny blocking piece to trigger the gun mechanism is like using a wooden stick to lever a large stone. It's better to make the firing rod larger to ensure that no accidents occur during use.
However, at this moment, the blocking piece on the firearm that Winters is holding does not require an excessive force to press, comparable to the trigger resistance on a revolver gun.
