Marlin Model 99M1 .22lr. Basically a model 60 action done up to look like an M-1 Carbine. Was my grand-dad's, my dad's, now mine until my kids are old enough. Ugly as sin, as been beat to he11, rear sight got lost (mounts on the scope dovetail rail) when my dad was in high school, front sight fell off when I was in college and I've never epoxy'd it back on. Still shoot very well with this rifle, even without the sights.
Ruger Mark II stainless standard .22lr. Picked it up when I was in high school for $90 from a buddy that bought it then got in trouble when his parents found out. Been swimming more than a few times going in after coons trying to drown my hounds, and killed more coons than I care to count with it. This pistol also spent time as a "loaner" or "trainer" when I was giving regular handgun training classes.
My wife's "gun I like" is her Marlin 1895 Stainless Guide Gun .45-70. I've spent a lot of hours polishing and refitting the action to make it smooth as butter. At a paltry 1792fps with Hornady Leverevolution 325grn FTX's, the ballistics aren't anything to brag about. She has other rifles that she can use (and does occasionally) in flatter shooting cartridges, but she just loves that rifle. Admittedly, I'm pretty jealous, it WAS my rifle that I hadn't ever shot before she took it over, now I'd be looking at about $1000 to buy and rebuild one like it, which is pretty hard to justify when I have about $500 into that one!
Here's a twist: Gun I just flat don't like, even though all of the numbers and every "gun guy" in America says I should: Glock 19. A company I was working for bought it for me as part of an experimental ammunition project I was working on back in 2004/5, so I own it. I shoot it well, and it does everything a semi-auto pistol should do, but I just don't care for it. If I had any of my own money wrapped up into it, I'd probably have sold it a long time ago, but since it was free, I keep it around as a nightstand gun. I just don't like it.
