I'll cheat and not limit it to 1. Favorite rifles and then handguns
1. M1 Garand -- because I'm a red-blooded American who grew up in the 60's watching WWII movies. And because it is a lot of fun to shoot as well. Not the ultimate battle rifle, but one that is full of history
2. FN-FAL -- this is the rifle I reach for the most from the safe because it is ergonomic, powerful, reliable and good looking. 90 countries can't be wrong.
3. 1874 Sharps -- drop dead gorgeous, extremely accurate and came at a pivotal time in our nation's development. Plus, Quigley can't be wrong, can he?
4. Finnish M39 -- I've been enjoying reading and thinking about the Winter War and the Continuation War recently. The M39 represents what a small, determined populace can do against impossible odds based on the independence of it's people...and marksmanship. Everything the Mosin-Nagant wanted to be...but wasn't sophisticated enough to think of.
5. AR15 -- I used to "hate" AR15s until I actually owned one. Now I have 7. They are infinitely customizable, sufficiently powerful, handy, ergonomic and a lot of fun. This one is set up just like I want it.
1. Les Baer 1911 -- I like most handguns but the 1911 is by far my favorite. Maybe I'm in the minority, but I haven't found them to be finicky or anachronisms, and I've been shooting them for 25+ years. The current crop are reliable, handsome, accurate and affordable. This Les Baer is by far the most accurate, tight and nicely made one I own. It is a pleasure to hold and shoot. Beautifully made, its action and trigger are like they were made by Swiss clockmakers. JMB really was a genius.
2. Browning HiPower/P35 -- The first centerfire handgun I owned was a Belgian-made HiPower. I learned to shoot automatics with that gun. After 1000's of rounds, I could shoot it pretty well. In a fit of idiocy, I sold it to a airline pilot I knew and regretted it ever since. This is one of the FN HiPowers that were out a few years back and I bought it as a replacement. It is nice and shiny but not quite the quality of my first...you never forget your first.
3. Ruger Mk II -- This is the first handgun I bought. I've had it for over 25 years. I shot NRA Bullseye with it, have run 10,000's of rounds through it plinking and it is still accurate and reliable. Now my 12 year old son has adopted it. When we go shooting, this is the one he wants. I suppose I'll have to go buy one of the new Mk III Hunters as a replacement for me.
4. Ruger Blackhawk, .45 Colt -- I had a great friend that I grew up with...from Cub Scouts and on. John and I took different paths in life...me corporate and he went the "good ol' boy" route. We never let a week go by though, that we didn't talk. When we were in high school and college, John and I would spend all day Saturday at my family's farm shooting. More often than not, I was shooting this Blackhawk and John was shooting his .41 Mag Blackhawk. We'd spend the week working up handloads and take them out on Saturday to shoot. We'd spend a lot of the time just talking and spending time together. We both shot our first wild boars these pistols. John fought in Gulf War I and never was quite right after that. He died of a brain anuerism in August 2006. I miss him.
5. S&W 1917, .45 ACP -- This one was made in 1918. I love the story of these pistols...speaks to American innocence as well as its ingenuity of getting materiel in the hands of its troops. The single action pull is crisp and light and the double action is like butter. This is a beautifully made pistol with commercial style finish. Its finish and lockwork are 98% It is a joy to hold and shoot.
