John Mahlon Marlin was born in Connecticut in 1836. His career started as an apprentice tool and die maker and he worked as a machinist with American Machine Works. During the Civil War, John worked at the Colt manufacturing plant and in 1863 he started manufacturing single shot pistols in New Haven, Connecticut. He founded his own company, Marlin Firearms Company in 1870. Marlin was making derringers and revolvers and then expanded into producing other firearm designs from there. The post war turbulence made small concealable handguns a desirable choice for self-protection and in turn, Marlin sold a lot of those types of firearms. Marlin took over production of the Ballard single shot rifle in 1875, which was popular with hunters and sportsman. Production of the Ballard rifle was discontinued in 1891. Continue reading

I have always been fascinated with old muzzleloaders and the gunsmiths who built them. Early vacations to Williamsburg, Virginia exposed me to Master Gunsmith Wallace Gusler, as well as the Gunsmith and Blacksmith shops in Colonial Williamsburg. The fact that a gun could be built by one man from start to finish has held my interest throughout my entire life. Continue reading

I guess at this point in my life, I could be considered a collector of firearms. Within my collection, I have a collection of long recoil operated shotguns. This would include Browning Auto 5s, Remington Model 11s and my most recent acquisition, a Savage Model 755A. All of the previously mentioned shotguns are based on John Browning’s designs. Like Remington, Savage Arms also licensed the design from Browning. The Model 755, at first glance, does not look like the other “humpback” shotguns I love so much, but the way the gun functions is very similar to the rest of the pack. Continue reading

If you want a rifle that has a great history, low recoil and good accuracy, the M1 .30 caliber carbine is an excellent choice. This carbine was issued in 1942 as an alternative to the larger M1 Garand. The military wanted a weapon that was not cumbersome yet had better long-range accuracy than a pistol.M1-1 Continue reading

In 1803, the third President of the United States, Thomas Jefferson, had just completed the Louisiana Purchase which entailed purchasing 828,000 square miles of land from the French for a mere 15 million dollars. This investment made necessary one of the most important expeditions in our history, the Corps of Discovery Expedition, circa1804-1806, more commonly known as the Lewis and Clark expedition.

The BAR Rifle

Long ago I bought all of the firearms I “needed” and, ever since, I have been buying the guns I want. My latest purchase of a Browning BAR rifle chambered in .30-06 goes back into the “need” category. The last few times I have gone on my morning walk up the mountain, I have been sent back home by big black bears. I always go walking with a rifle, which is usually light in weight and chambered in 5.56 x 45mm. Continue reading

This Winchester cartridge has been an iconic round in the hearts of deer hunters and lever action enthusiasts since its debut in 1895. The .30-30 has remained a very popular cartridge in the United States for well over a century and is still going strong. Continue reading


Glock 17

Over the years, Glock has become a “household” word, at least in the Urban Dictionary. There are many different models of Glock pistols, but when I envision a Glock, my mind goes back to the 1980s and I picture a Glock 17. Though the pistol has gone through some noticeable design changes in the area of the grip and the recoil spring and guide rod, the functioning and safety features have remained the same.
