"to tell the truth i'd scare me too"

Great line

It's sad that this song and Mayhem, Maybe are two of the best on Broadsword, even though they're both extra tracks.

Inspired by:

"guns don't kill people, people kill people."

This guy is going out to kill someone, and his gun is like, "yeah, let's do it." But then the gun reminds the man that he (the man) is going to get the blame, and not the gun.

"it's not the gun that kills but the man behind."

I love Jethro Tull.

This could be the only musical recital of firearms history ever written. Here's some selective interpretation and clarification for those who might not be firearms aficionados:

"Match, wheel and flintlock, they all caught your eye. Pearl-handled ladies' models, scaled down to size. I am the peacemaker, so the theory goes. But I don't choose the company I keep --- and it shows."

Matchlocks, wheel locks and flintlocks were all early forms of ignition methods for black powder firearms until the invention of various forms of percussion priming devices in the 1800s. The "Peacemaker" was the marketing name for Colt's Single Action Army (SAA) revolver, which was popularized by Western TV and movies. It was issued to US military troops through the early 20th century.

"Maxim and Browning, they helped me along. Stoner, Kalashnikov --- thrilled to my song."

This lyric refers to 4 renowned firearms inventors, pioneers and developers. - - Hiram Maxim, among other things, invented the first widely used military heavy machine gun.
John Moses Browning was perhaps one of the most prolific firearms inventors in US history; among other famous weapons, he invented the Winchester Model 12 pump shotgun, the M2 .50 caliber heavy machine gun (still in use by the US military to this day, 100 years after its invention) and the M1911 .45 caliber semi-auto pistol, used by the US military for over 70 years.
Eugene Stoner developed the original Armalite Rifle (AR) in the 1950s which was subsequently adopted (in a modified form) by the US Army as the M-16 issued during the Vietnam Conflict, and is still in use (although even more modified) by the US military and scores of countries around the world.
Mikhail Kalashnikov was the inventor of the Avtomat Kalashnikov (AK-47) rifle which was first introduced after WW2 and like the AR, is still in use in a highly modified version by Russia and China and many of the former "client states" of the old Soviet Union.

"Now one of me exists, for each one of you, So how can you blame me for the things that I do?"

Likely a reference to the 'gun culture' and widespread ownership of firearms in the US, where there are supposedly enough firearms that have been sold to arm every man, woman and child...the inference is that with that many guns in circulation, something bad is bound to happen from time to time.

"Now I take second place to the motor car in the score of killing kept thus far."

This is a factual statement regarding the number of people killed annually (again, presumably in the US) by automobiles as opposed to those killed in firearms incidents. There are far more people killed by cars than guns.

"And just remember, if you don't mind --- it's not the gun that kills, but the man behind."

A sage statement to remember for those who would seek to demonize firearms and seek ways to ban them. Guns are just pieces of machinery - inanimate objects which do nothing until used by a human being.
