I agree with dsk . . . . The mag's are easier to insert, with the slide closed, when not full.
In fact, I have several that will not allow you to insert a completely full mag, without hitting
it very hard.
There is a second consideration:
Anyone that has been shooting for a long time with the same gun or type (full size 1911
for example) does a subconscious count of rounds. I had one time where I had just gotten
an eight round mag for my 1911. I had multiple seven round versions that I was shooting.
I was loading all mags to capacity. - - - When the eight round mag went it and was emptied,
I actually stopped to see what had happened when the slide did not lock back after the
seventh shot. - - - Keep in mind that this is SUBCONSCIOUS, presuming you are at least
average intelligence.
As such, you will not be able to control it unless you are spending time thinking about
THAT in place of what your shooting situation is.
Another way of looking at it is . . . consistency. Do you shoot a wide variety of different
capacity magazines? If so, then you will not have that situation come up.
(consistently inconsistent?)
