Bureaucrats and gun laws are funny, except the for part where they intrude on your freedom for no good reason. So apparently, you cannot knock around in the wilds of New Zealand with a handgun, but you are free to go home and create your own suppressor?
All are correct that a small carbine cambering a "pistol power" cartridge is pretty darn useful. They are relatively small, light, carry well, but are much easier to shoot accurately than a handgun. I don't know if the creators of the TV show "The Rifleman" truly understood this, but it seems they got it right one way or another. Then on top of all that, they gave Lucas McCain pretty decent from the hip rapid fire capability. As many know, that combination of attributes was the reasoning behind the M1 Carbine. It was not meant for "front line" combat, but was something for rear area usual noncombatants to use much more effectively than the 1911 pistol should they become combatants.
I bring up the M1 Carbine on occasion when discussing "assault rifles" with those who blame the availability of the AR-15 for a number of societal ills. Most of these people are not well versed in firearms history. I point out that the attributes of an "assault rifle" are primarily the following: relatively small size, relatively light weight, semi-automatic, a moderate power cartridge so you can carry a lot of ammunition, and the capability of using high capacity magazines for a rapid reload. Pistol grips and being black in color have little to do with it. The M1 Carbine has all of the attributes I listed. Many knowledgeable gun people give credit to the German Sturmgewehr 44 as being the first assault rifle. While the StG 44 is select fire, based on my definition above, I maintain the M1 Carbine was the first assault rifle. If it was not, then I argue the selective fire M2 deserves the nod. It seems combatants decided the M1 Carbine was a pretty good front line weapon in some situations. I believe that is why the selective fire M2 was created. But, I digress.
After schooling up my AR-15 hating "friends" on the M1 Carbine, I point out that in the 1960's, the US Government, via the Civilian Marksmanship Program, would sell you a surplus M1 Carbine for $20 (Twenty bucks. I didn't leave off a zero. Now, $20 was a bit more money back then, but it was still a pretty good deal.) I then point out that "assault rifles" have been available for a much longer time period than my AR-15 hating friends realize, and that the US Government used to sell them to US Citizens. In fact, they ran out of them to sell. So, with that, it is pretty hard to blame "recent widespread availability of assault rifles" on whatever modern problem they want to blame them for.
As my eyes have aged, I can no longer aim with open sights as well as most rifles will shoot. Happily, we have a number of other choices nowadays. I have even figured out some pretty good iron sights for "handy" rifles using aperture rear sights with the right inserts in the small unobtrusive Lyman 17A front sight.
Finally, the Ruger 10/22 is on my list as "one of the four or five guns everyone should own." If I didn't know better, I's say John Moses Browning had a hand in its design!
Sorry for the long post. I hope I didn't get off topic too much, and I hope I added to the discussion.
