The "wall" comes from relatively current articles about trigger technique using mostly strikers or LEM, not DA or DAO. I too do not like shooting step by step, however, to develope the correct muscle memory with say a HK LEM or any striker, good shooters press straight through and other good shooters say they find their sights in take up pausing briefly at the "wall". Is one better than the other?
Both are useful in the proper circumstances.
"The wall", as pointed out above is not new. It's just a newish term that "comes from relatively current articles about trigger technique". As chemcal noted.
It's staging the trigger in a semi and whether to do it or not. Or when to do it. This was mentioned earlier in this thread by a couple of different folks. It makes zero difference whether it's striker fired or hammer fired. As mentioned by others it was common in military rifles for generations.
All semis that I'm familiar with have some take up of the trigger. There is slack in the trigger, that is, the take up before you get to the point where the trigger breaks. Different designs of triggers will have a different feel but essentially they all have this in common. The point here, of the OP's question, is do you take up the slack and pause
before pulling through the trigger break, or just pull through?
This has been discussed for a long time by shooters and there are different advocates. Mostly though, for most folks, both have their place and are useful. For a well aimed shot at distance the pulling through the slack, or take up, and firing when ready works well. Placing three shots into a close target in one second, trying to feel a pause, is well a bit harder and I don't worry about it and pull straight through. Some top level shooters may be able to but that ain't me.
A common thing is the "gun culture" is for a gun writer or a gun trainer to attempt to distinguish themselves by coming up with a new term for something that is old. Sometimes this is because they have an insight into something or are advocating a new approach (think of Jeff Cooper's "surprise break" of the trigger for example). Other times it's for self promotion. "The wall" seems to fall into that. It's an older discussion of trigger prep.
