LOL the great thing about it is that almost every gunshop I've been to is a "Glock Armorer".
Yeah, most of them will be, its a one day course...not too bad, I went through it in March... Its actually alot of fun if you enjoy firearms and the insides... theres not much to a glock
There are a few things you wan to make sure of, though, when reassembling, you need to make sure that the slide release is put in after you put the first small roll pin back in but before you put the larger roll pin in, you will not get it in otherwise. If you reverse the steps, too, your slide lock will not be in the right place, the spring end will fall above the small roll pin, which can cause malfunction of the weapon.
You will have to take apart the trigger bar from the trigger, you will see the crossbar, and most likely it will be blank, if you see a + sign, you have an 8lb trigger, if you see a -, you have a 3.5 trigger. There is also an option just to buy a NY1 and NY2 trigger spring, probably easier for you?
