This is not exclusive to Airguns since trends of Airguns are highly influenced by what type of Real Steel Pistols are popular to people. This is often based on what people see portrayed in movies and TV Series, and also promoted online. There is for sure an overlap in what is popular and it is hard to say what is influencing what? Is it the popularity of Pistols out in the real world that influences what we see being used in the movies and on TV? Or is it what we see in Movies and TV that influences our choices of pistols out in the real world? Perhaps it is a combination of both?
My list is based on my own personal experience and does not represent the entirety of types of Pistol designs available.
It has been way too long since I got to go to the gun range and shoot my "big boy" guns! I say that sarcastically, sure my real steel guns are fun to shoot but it sure costs a lot of money and basically all we really do is shoot paper targets. Shooting at papper targets is fun for a while but I kind of enjoy shooting my airguns at pretty much any type of target I choose to shoot at. And of course any time I want to and for pennies per shot.
So getting back to Range Day shooting my real steel big boy guns ;) I went with a couple of buddies of mine and we shot a nice variety of guns. My Norinco NP-30 double stack 45 cal 1911, my Wyoming Arms Parker 10mm, a couple of my friends Glock 40 cals, my Norinco NP-34 P228 and Norinco Tokarev Type 54 9mm pistols, my Chiappa 1911-22 and ISSC M22 22LR pistols, a nice Sig Mosquito 22LR, my buddies S&W M&P 15-22 22LR rifle along with my ISSC MK22 SCAR 22LR rifle and my friends mighty custom Ruger Mini 14 in .223 caliber...
It was a cold day but a really fun day and it gave me a chance to really use my iPhone 6 plus camera for its slow-motion capabilities in a decent lighting situation.
Enjoy the footage of these "real guns" shooting in real time and slowed down.
