From my perspective, it's matter of need (want?) and money.
Since I use the 'Call your shots' technique...

... I don't need a laser or a MantisX to confirm the POI, especially when dry firing.
What I
do need is a trigger that resets to dry fire practice self defense and action pistol shooting.
For example, my indoor practice stage is pictured below.

As may be noted, there are 3 white barricades, around which (red arrows) I engage 4 sets of 4 small targets (green arrows) with 2 shots per target, moving (yellow arrows) and reloading from the start position to positions 1 - 6 in sequence (white numbers).
Furthermore, I vary the stage execution by sometimes moving right to left, then left to right... shooting right handed, then left handed... and shooting two handed, then one handed.
Obviously, a 'single shot' system won't work for me... I need a resetting trigger.
Currently, I remove the trigger connector to make a 'mushy' resetting trigger so I can 'run the stage', but I'd rather that the trigger have a more realistic 'feel'.
The DryFireMag will (hopefully) address the trigger 'feel' issue, but, unfortunately, given that the DryFireMag doesn't drop freely and must be stripped from the well, it seems that reloading during the run must be sacrificed... plus, given that I use 6 magazines, at $100 per mag, I'm not willing to spend $600 on DryFireMags.
So, my current plan is to sometimes practice without a trigger connector (to practice reloading while moving) and sometimes practice with the DryFireMag (for the 'realistic' trigger).
We'll see how it works out.
Best regards,
Bob
