At this point it's fairly common knowledge in the gun community that using optics on handguns has a clear speed advantage over iron sights. However, I do run into the odd person who insists that it is a gimmick, or a preference, or any other argument to justify not using one on their handgun. I got bored, had a thought, and figured I'd share it here. I won't go into the science here, since it would take an awfully long time to explain, but I will give some simple, straightforward data that backs up what I'm talking about.

This is in the context of IPSC, so the skills that are tested between sighting systems are practical - fast target acquisition, ability to shoot the same target predictively, accuracy at speed, shooting on the move, transitioning between targets, speed at distance. In this context we have a very valuable apples-to-apples comparison - two divisions with identical rules and equipment, the only difference being the use of irons or optics - Production, and Production Optics.

I went through the results of our past 4 national championships and compared the raw times of the champion in both divisions. Keep in mind, while Production is beginning to die off as PO and Optics gain popularity, there are still very good shooters in Production.

2022 - PO beats Prod in raw time by 22.3%
2023 - PO beats Prod by 16.3%
2024 - PO beats Prod by 16.3%
2025 - PO beats Prod by 14.9%.

We can throw in some raw time data from around the world to get a more accurate picture. At 3 of the top international matches this year we have;

Eric Grauffel (PO champion) beating Mason Lane (Production champion) by 8.2% at the World Shoot.

Grauffel (PO) beating German (Prod) by an almost identical margin, 8.1% at the US IPSC nationals.

Grauffel (PO) beating Michael Stepan (Prod) by 11.3% at the CZ Extreme Euro Open.

These matches I picked were wildly different in their challenges. The US IPSC nationals was insanely technical, with many difficult shots, distance and moving targets. The World Shoot was mostly hosey and speed focused. The extreme was somewhat in the middle. Regardless of the challenge, the data from high-performance shooters does not lie - optics on handguns is consistently 10%+ faster than using iron sights.
 
Thanks for that, excellent info 👍
My wife, myself and a couple we know spent an entire Saturday running drills to test this. We all have the same pistols in both irons and optics, for me it’s G19’s, the wife M&P’s, our friends both shoot variations of Sig 320’s. Our results were exactly like yours, without a doubt optics are faster. No matter how we set up stages to run the optic equipped pistols came out on top every time for every one of us.
All 4 of us shoot multiple competitive disciplines
 
I did something similar this past summer. I have iron sight slides and optic slides for all three of my pistols that I would use for competition. While my splits weren't dramatically different when running the guns as fast as I (reasonably) could (slight edge to the optic slides), my group sizes were definitely better with the optic slides.

Certainly not a gimmick in my book..
 
Kinda makes me wonder if the slight change in the speed difference over time has anything to do with the increasing popularity of enclosed optics on pistols vs the older open emitter models.
I’ve got both in my fleet but still choose to compete with either an SRO or a Romeo Pro Max. I find the closed emitter optics have some thick housings.
 
That’s what I was thinking, more limited field of view results in them being ever so slightly slower.
At a certain level the "window size" and enclosed vs open only matters in certain circumstances. I picked up a friend's Shadow with a holosun 507c, an optic with a pretty thick housing and small window size, and it didn't slow me down one bit. The only time I noticed was shooting strong or weak hand only, more delay finding the dot if I lost it. That being said... The Apex fusion, 507comp, or RTS3 are really nice to compete with.
 
There is a really good reason why police are switching over to optic mounted handguns. Vancouver Police were using an optic mounted P320 until they had to discontinue use due to safety concerns with the P320 pistol and they're now back to their old .40cal P226.
 
My only reference point on closed emitter optics is the Trijicon RCR. Window is similar to an RMR, maybe slightly larger, so pretty small, but they integrated the battery housing into the shroud which makes it pretty thick. Definitely a SHTF optic if there ever was one, but I’ll take the SRO any day for competition.
 
I like that you compared PO vs Production as they are the exactly the same guns and rules sets. Production is a dying division thou.
If you throw standard division into the mix and just look at the raw times it’s a lot closer than 10%
Other than the extreme match you referenced Eric’s raw times were almost beat by a standard shooter at the US IPSC nationals and the world shoot.
 
Careful comparing Standard though. Many of those shooters are using Major scoring so they don’t really worry much about shooting a C vs an A if they are fast due to the scoring.
 
for gunfighting - I don't use sights ...

Im a C.A.R.S guy, for over 30 yrs, thank you Paul

don't use sights: draw rotate start shooting

insert sights for 'longer shots' ...

if you need longer shots, transition to your shotgun, carbine etc :0)
