If your handwriting is like mine, you may want to type it out on a word document, print and sign by hand.
It goes without saying that it should be polite and professional.
Before you send the letter it's wise to have someone proof-read it. Just because you understand it doesn't mean that anyone else does. Have a thick skin and ask the proof-reader to be honest and use a red pen to mark the mistakes.
I don't want to disparage or insult anyone but even a polite and professional letter ought to be grammatically correct. And I also hate to sound like a grammar Nazi but I've seen too many forums where people use one continuous sentence without any punctuation, capitalization or correct spelling.
Remember that paragraphs are your friends. Put plenty of space between sentences that convey a different topic on the matter. In other words, use a separate paragraph when you are going on to a separate thought or topic.
Don't write a letter like you might type a short e-mail, text message or post on a forum.
Again, I apologize if it sounds like I am insulting anyone's intelligence but what and how you write leaves a lasting impression on someone.
If you are trying to convince a legislator, who's sitting on the fence regarding gun issues, then you aren't likely to impress them with sloppy writing. They may regard you as some stupid, uneducated, smelly red-neck that hates the government and is nothing but a hate-filled "bitter-clinger."
After you have written your letter, read it out loud and very slowly. If it doesn't sound right; then there is probably something wrong with it and needs corrected.
Another technique is to read the letter from the end - backwards. That sounds a little crazy but believe it or not you can find lots of mistakes that way.
Here are some links on how to write your legislators. Some of these links are from organizations that are usually hostile to gun owners. Nevertheless, what they say about writing a legislator is true.
Besides, they have been doing this for years and look at the make-up of congress. Let's use the same letter writing tactics that they have so effectively used for years against the gun control agenda that most of them promote.
Also keep in mind that what one person writes to their congressman about statistically represents what another 1000 constituents are thinking. Let that sink in. Your voice represents what a thousand other voters are thinking but aren't expressing. So if thirty people from the same congressional district write a congressman about the stupid NFA of 1934, that means that there are probably 30,000 voters in his or her district that feel the same way.
