My favorite is probably my Glock 21, with the grip reduction, at my side all the time and because it's there, I have shot more stuff with it more than any other pistol I own. Snakes, squirrels, opossums, jack rabbit and cottontail, Deer, and them pesky cardboard critters.
Other favorites, like your children you got to give them all equal love.
My 6" 686, with over 60k rounds through it.
model 41 S&W, with 2 barrels and it is absolutely accurate.
S&W 940, daily pocket gun, but with 147 grain bullets is a bet winner.
S&W 5" 625, love it. May shoot it Saturday at the personal protection match, by the way you can't shoot it in IDPA.
My Para LDA C7, I may shoot it as well.
Rifle, My 788 Remington in 7mm08, and .222, both shoot better than they have a right to.
My fiberglass stocked model 7, in 7mm08, 6 pounds with scope and a single set trigger, so much fun to carry and it shoots good.
Both my M40 sniper rifles, absolute accuracy out to 1000 yards.
All 6 of my AR'S, tuned and shoot good.
My Sako, .338 win mag, weird, off the bench it won't shoot unless you really lean on it, out in the field, it never misses.
My standard grade M1A, with national match sights, I do truly believe, if I can see it, I can hit it.
Shotgun, My 1187, premier, and then my 2 870's always work. I have a Benelli super 90 M1, but I don't like the recoil impulse.
My favorite field gun, because I don't miss much with it, is an Italian Silma, 12 guage, imported by Legacy sports, these were available at Academy, for around 550-600 bucks and a bargain.
