In all reality, you are more likely to find .41MAG ammos on the shelf than you are 10mm. As far as components, what makes a .44 cartridge makes the same .41 cartridge, etc, etc. .41 bullets aren't on backorder, either...
You know... I got it. Everyone has their favorites. My first centerfire was a .41... had it been a .44 or .357 I don't know if I would be bothering with the .41 like I do now, but it is what it is. As I mentioned previously... I no longer have a .357 or a .44... the .41 fills that role perfectly for me. YMMV. Need not be present to win. Do not fold, bend, spindle, or mutilate.
