Quoted: All it takes is one force on force class using Big Dots back to back with traditional sights and nobody here would even consider traditional sights for a self-defense pistol.

Uhhh.....

I've used XS sights and regular sights. I've done FOF training.

You won't find big dot sights on any of my handguns. They work OK at close range for a flash sight picture, but they are a mess in the accuracy department at longer ranges where you need to be more precise.

Quoted: I wonder if DELTA uses them.

They don't.

Quoted: From the book I read they use a quick sight picture focusing more on the target and just bringing the pistol up and shooting.

This is called a "flash" sight picture or a "threat focused" sight picture. It is appropriate for closer range engagement with a handgun, anywhere from 3 yards up to 10 or 15 depending on the conditions and the shot that needs to be made and the skill of the shooter.

The procedure is to focus on the target and then simply index the weapon on the target, essentially placing the sights on top of your focus and then executing a good trigger pull. Done properly it is every bit as accurate and effective as sighted fire at short ranges, but is typically faster than sighted fire.

I practice it in my house against the painting of my great Grandpa and could see how you could be pretty accurate (at close range) without even focusing on the front sight.  But I've yet to really try it at the range even.

The "threat focused" style of sighting is actually what you are most likely to do in a real life engagement, as people tend to focus on the threat and then index their weapon on the threat. You can see this demonstrated by putting people through shoothouses with threat targets and non-threat targets. You'll see people actually shooting the weapons in the hands of the bad guy targets because that's where their focus was when doing target discrimination.

Either way, I don't think the big dots are a solution to all problems.

In that you would be correct. Sight preferences are intensely personal things, and the same setup doesn't work for everybody equally well. Something like a big dot sight (at least up front) may be the best solution for someone who has problems seeing the front sight at all because of defects in their vision, or someone who has minimal training time or minimal commitment to training.

For most people trigger control is a FAR more important issue than sight alignment.

I think it's got more to do with practice and putting into practice what works.  I far prefer a traditional set of sights.  I've shot at quite a distance and can not see how I could do that with those on it.  I have witnesses of hitting a man sized torso with my M9 at 200 yards.  I know it sounds crazy, but oh well.

I regularly shoot my handguns at 100 yards offhand and hit what I am aiming at. It's likely that I won't ever need to shoot that far to defend my life, but there are no guarantees in life so I do it.

It's also superb at teaching proper trigger control.

Quoted: Thank you JohnWayne77 for the explanation.  I'm afraid some people will think I was goofy for saying what I did.

Somebody on this site will think you are goofy even if you were a former Delta guy who killed more people than the plague.

Such is the internet.

I will try and incorporate more of that shooting at the range.  I just have been doing it dry firing at present.  And I haven't shot my pistols as much as I'd like to lately.

I'd also suggest getting Crimson Trace lasergrips. The laser is the single best "threat focused" sighting system you'll find, but they aren't as durable as fixed sights so practice with both.
