After stating and participating in the "Dog Defense" thread, I have come to the conclusion I should get a handgun "and all that goes with it." This thread is to discuss what should go along with acquiring a handgun.
I have owned rifles and shotguns, but never a handgun. I have fired a few handguns, but none recently. I was never interested in handguns enough to pay them much attention. So this is new business for me.
My favorite brother is in law enforcement and I will lean on his experience pretty heavily. I a going to pay attention to what you guys recommend, too.
My expectation is some study of handguns, and enlisting my brother's advice through purchase and beyond. I hope to try several calibers of handguns at the shooting range.
After that I hope to have are extremely narrow range of candidates.
I understand there is a tiny possibility I can get some combat arms / close quarter’s combat training through my brother.
Gun, cleaning supplies, ammunition, trigger lock, and ?
The "what do you need" part of the question is pretty simple. If you have other guns you should already have cleaning supplies, eye/ear protection, secure storage, etc.
As for which gun and caliber. Stick with a major manufacturer in a common self defense chambering and you should be fine. Most folks I know will tell you > or = 9mm/.38 Spl +P. This is the part of the issue that always goes off the rails and turns into a Ford vs Chevy; Ginger vs Mary Ann discussion.
If you're in an area where political correctness counts it might be prudent to stick to something very similar to whatever the local police carry.
If there is ANY way you can do it, scrape together the time and funds for a good pistol class.
