I have experience with the older Marlin-Marlin model 1894 in .357 magnum. That is, pre-Remington Marlin. Compact, reliable as can be, no feeding or ejection issues, can be fired very quickly without using to lose sight of your target. .357 mag ammo is super common and easy as pie to reload your own. And, of course, you can fire .38 special ammo, and use the same reloading dies for both. Been reloading these calibers for over 50 years now. The 1894 hold 8-10 rounds or so depending in which caliber. The only slight drawback is the same for any lever action with tubular magazines. Stay away from pointed bullets. There is a danger of the Pointed tips hitting the primer and setting off the round in front in the magazine. Self defense. Totally. It will not be as accurate as a good bolt action. At 50 yards and less, for self defense, you are well armed. And, in pistol calibers, there are 357 mag, .44 mag, and .45 Long Colt. I've not seen any in .41 mag. I read quality under Remington ownership took a dive, but since Ruger acquired Marlin, all is well, though you'll have about $1000 or more into it for a Marlin. I think I paid around $300 new for mine. Reloading is slow compared to semi-auto, but 8-10 rounds should be enough. Never had a miss fire, but if I did, just a quick rack of the lever loads a new round. There are other makers of less expensive lever rifles, such as Rossi.
