^^^ Neither of the choices belong anyplace but in a gun safe as curios.
The Lebel because, well... it's a Lebel.
The .25 because, well... it's a .25
Neither is suitable for any sort of self defense (although you can leave the 25 loaded for the rest of your life and it's not going to weaken the magazine spring).
Get some training.
Get a CCW.
Buy a modern handgun of your choice to add to your "Historical Handgun Collection, be it ever so humble".
