There are many aspects to "proficiency" with semi-auto pistols.

I shoot well enough for my purposes and for the sorts of competitions I
enter. At 25 yards, I can put 10 rounds into a circle about the size of
a softball with my 9 mm and .45 CZ's. With my revolvers, the circle is
about the size of a honeydew melon. At closer distances, the circle is
smaller. I'm sure that is far better than you shot with a sidearm when
you were a marine. I'm pretty good with shotguns and my .22 LR rifle. I
have very little experience with larger caliber rifles.

I didn't have to qualify with a sidearm when I was in the Corps. We did
do familiarization fire with the M1911. And we shot the hell out of the
M16A1 at 200, 300 and 500 yards. And we had to qualify each year with it
in the Reserves.

The "handling" practice I do has prepared me to quickly clear problems
with firearm mechanisms or faulty rounds.

Is that so you can pump as many rounds into a "home invader" as possible
before your front door fully opens.

I think I'm proficient enough with firearms. Sport shooting is only a
part-time hobby for me.

Hobby, it appears to be an obsession with you.
