In my humble opinion, if you want to get into guns, start with the Glock or the AR. They are the simplest platforms out there with plenty of free and readily available and accessible information on both.
The aftermarket support is unbelievably plentiful, everything from amazon.com to your local pawn shops and gun stores have parts and accessories for your Glock or AR. Unquestionably, the Glock and the AR platforms are the legos of the gun world.
Easy to take apart, easy to fix. There is no such thing as a truly custom AR or Glock and there is no need for a gunsmith, for either. An novice can assemble a complete AR in under an hour or two. A person who has never touched a gun in their lives can easily repair any Glock with a 5 minute lesson.
If you’re ever interested in learning a new “skill” a simple search on YouTube will turn you into a Glock or AR semi professional, since there are no actual professional skills needed for either, just a willingness to learn and try.
Before you know it, you’ll be telling your friends how to fix their Glocks and ARs.
It would be nice if everything in this world was as simple as the Glock or the AR. You could literally fix everything yourself.
