Not sure I will make a video about this topic but it has something that has continued to come up and something that much better shooters than man also seem to discuss or talk about.

When I say the margin of error when it comes to shooting mainly I mean is there is something that work when they are done perfectly right, but require a very ideal situation. Items with a larger margin of error allow you to achieve good results without the required ideal situation. Mainly where i see this coming up is draw, grips, and reloads. With my glock gen 5 the said of the grip is a flat plane, this allows me to place my support hand in a few different spots and still achieve a pretty good grip that would remain consistent throughout a string of fire. With guns that have more “ergonomic” style grips there are curves and slopes on the grip. When placing your support hand on the gun if you are too forward on the gun your grip will likely start sliding forward and will produce inconsistent results.

I started encountering this when I had to produce results under stress and against a timer, when you are at a flat range and not trying to push time you are given a false sense of performance as you have the opportunity to generate the perfect grip and everything feels good. However if the ability to hit an acceptable grip under stress and time constraints you will quickly realize that the larger margin of error firearm or equipment will produce better results. This does disappear though as general skill progresses.

For example in my area, it is much easier to get a decent grip on my gen 5 glocks, than it is on my p30, but if I had a good enough well practiced and consistent grip my likelihood of error on the gripping of the p30 goes down.

TLDR the flat range is deceiving and when starting out you should definitely choose a gun/holster/mags that have a larger margin of error. As you progress into M class or GM class shooting your skillset has likely progressed enough that this isn’t as much of a factor.
