So, after most of a month shooting nothing but the micro Glock 43, I took a fun day at the range Tuesday shooting normal-size Glocks again...
The Robar Glock 17 and my former G19 carry gun allow me to get my Glocking in without having to unholster the G19 on my hip. Both have 3.5# connector/NY1 spring carry-type trigger setups in them, despite the fancy-looking aftermarket triggers.
After all the time with the little Glock, going back to the big guns made things feel easy again. The 3x5 at seven yards was a clout shot again, and I was again able to go fast on the 8" circle without feeling like I was hanging on to a popsicle stick for dear life.
And then Wednesday, it was back to work with the Sig project...
Trying to do any kind of speed on a 3x5 at seven yards with a DAO
trigger...even a smooth, light, seven pound DAO trigger...humbled the
hell out of me after a month of striker-fire-only shooting...
When I commented that you'd see an initial performance deficit moving from either the SFA to the DAO or vice versa, a friend asked on Facebook:
"Is
it because you build habit through repetition for a certain breaking
point and changing that breaking point throws you off? Or, will a
skilled individual always be able to shoot faster while staying accurate
with a striker fire vs a DAO similarity to the way a skilled shooter
will always able to score faster follow up shots with a 9mm vs a .40?"
And the response is where I blew a lot of the morning's keystrokes:
"That's kinda two separate questions:
1)
You're going to notice a performance deficit going back and forth
between triggers, no matter whether going from a shorter, lighter one to
a longer, heavier one or vice versa. This is why I get so hair-pullingly
frustrated when people talk about "carry rotations". If I didn't have
to shoot a bunch of different guns for work, I'd be putting 90% of all
my trigger time into my carry gun, and that's the only one I'd be really
serious about building performance with.
2) A
skilled shooter is always going to turn in faster blind splits with a
shorter, lighter trigger. If really smokin' Bill Drills are your metric
for what makes a good carry gun, then there's your answer. 
However there are some really good discussions in the archives at pistol-forum.com
where smart folks like Wayne Dobbs and Darryl Bolke talk about why
maybe raw, blind splits aren't that important in a gun that's used as a
people-management tool. Can I turn in faster splits with my Glock 19
than my P250? Sure. I can probably turn in even faster splits with the
Wilson 9 or my pimped-out Grayguns 320. But I can absolutely drive that
250 as fast or faster than I can process the visual information of
what's going on on the far side of my front sight."
