Hello all, my first post on this forum. :newbie: I'm going to be buying my first handgun within the next couple of months. I've pretty much settled in on the Glock G22, a .40 S&W handgun, although I may still switch to a 9mm, in that case the Glock G17. I'm buying for defense purposes, but I also intend to have some fun shooting targets (and, of course, what good does it do me for defense if I don't practice with it?); it also needs to be suitable for my fiancée to fire as well, which is why I've discounted the more powerful calibers (at least for this first purchase). Anyway, the caliber/make of firearm isn't the point of this post, although input on that is still appreciated. What I'm more looking for right now is what a first-time handgun buyer needs to know -- not from the legal standpoint (already done my homework there) but in terms of ammo, maintenance, et cetera. For example, from what I've read a hollow-point round is probably my best bet for a defense ammunition, but what about general target practice? I would imagine, for example, that a full metal jacket round would be a "cleaner" round to fire (in terms of gunk left behind in the barrel that needs to be cleaned out) than the softer lead, but does the harder metal produce more wear? (Obviously if I choose a different type of ammo for target practice than for defense I will practice with both types, just use the "practice" ammo more frequently, especially for casual plinking.) Also, what will I need for maintenance? Obviously a cleaning kit (which I understand Glocks include), but I've also seen "benchmats" for sale -- is that something I'll need, and if so (or even if not) what is it for? Will the gun's owner's manual include everything I need to know to properly maintain my firearm? Also tips on proper storage would be appreciated -- I'd assume low-moisture environment, but don't know about recommended temperatures, for example. I'm not new to shooting -- I've fired a variety of rifles and shotguns, and have earned NRA Expert Marksman for the .22 pistol -- but I have never owned a firearm nor been responsible for cleaning or maintaining any firearm (beyond ensuring the weapon is cleared and properly stored within a safe). As such, I'm trying to learn all I can before I commit to such an investment, especially how to protect it and ensure I get the most out of it. I would also appreciate suggestions for necessary (or highly recommended) accessories for a first-time gun owner; I do happen to have a tactical flashlight, as well as eye and ear protection, but that's it.
