When you Google videos(posted among the links) of a person with an Airsoft Glock or Air guns shooting better groups than most folk can on range with a AR-15(or PCC): Them you have people saying "I'm better throwing this gun towards" or barely connecting most hits at 25 yard with an actual pistol- Haven't you found anything suspicious of an platform with much less point of contact being very easy to shoot?
Did you actually watch those videos? You can see the pellets from the Glock going downrange sometimes and they're going all over the place, they aren't good groups at all, in fact, what I saw was that he was missing the entire target most of the time.
The second video didn't show any groups shot at all nor did it state at what distance he was shooting the reactive targets.
Not to put to fine a point on it, but if you're going to post videos to prove that people shoot much better groups with Airsoft of Airguns, you need to actually find videos that show people
shooting groups with airsoft and Airguns, not just random videos of people shooting airguns and Airsoft. That's just a waste of everyone's time.
I did watch the one about the Swiss Arms CO2 pistol and it didn't seem to be shooting great groups. The one group he showed was about 6" at 11 yards or so. That's ok shooting, but it's possible to shoot much better groups than that with a firearm (or a more accurate air pistol) at those distances. Looks like he got maybe 10 hits on the 70yard target out of 3 magazines (54 shots). Again, not bad, but not amazing--certainly not evidence that people shoot way better with airguns than they do with firearms. I took a pistol class some years ago and everyone made hits on a bowling pin at 50 yards with centerfire pistols--two people actually hit it on the first shot.
As far as why some people might shoot airguns and Airsoft better than firearms.
My take is that people tend to have less issue with flinch when they shoot Airsoft/airguns but some people do flinch when shooting firearms.
Having shot a ton of ammo through a variety of airguns and firearms, I can tell you that the accuracy is pretty similar.
However, if a person has developed a flinch, or has trouble with flinching, they will tend to shoot firearms much more poorly than they will something like Airsoft of an airgun which has very little recoil and discharge noise and creates no flash/blast.
That doesn't mean that Airsoft has no training value, but it does mean that a person using Airsoft/airguns to train needs to understand the limitations of the system.
Some person who claims to shoot airsoft way better than firearms said:
Basically I can take out a bullseye from 25 yards with my airsoft pistol.
I think that perhaps some hyperbole is present in this statement. You can watch Olympic airgun shooting--people using airguns that cost thousands of dollars, competing at world-class levels to get a feel for how well these amazing shooters can actually shoot airguns that are far more accurate than any airsoft. Then realize that all Olympic airgun competition is shot at 10m (33 feet).
I think it would be entertaining to watch someone who could really "take out a bullseye at 25 yards with an Airsoft" with any level of consistency but until I see it, I'm going to remain a bit skeptical.
If actual powder-burning autoloading pistols can be so easily used to plink 50 yard targets- Then why most person can barely connect their shots at 30 yards with an pistol without stock and foregrip with limp-wristing recoil and 6lb trigger pull? Why Mr Gun Jesus was shooting worse groups with an M1 Carbine than folks with Air guns linked let alone a mouse gun?
This is sort of a hodge-podge of "evidence". You've got different people shooting different guns at different ranges and for different purposes.
The airgun folks are shooting primarily for accuracy while the firearm videos are focusing on speed as a major concern. I don't care who is shooting, if accuracy (group size or hitting a small target) is their main concern, they will shoot better groups than when they are trying for speed in a timed competition.
You need to find some apples-to-apples comparisons, preferably by the same people, done at the same kinds of ranges and with the same goals in mind.
