I have carried various .357 mags, .45s, and a .44 mag and ultimately came to believe the 10mm is the ultimate round and the Glock 20 is the ultimate platform for that round. I have a Glock 21 in .460 Rowland that I thought would be just right but it’s too much power like the .44 mag. The 10mm surpasses the .357 magnum in stopping power and approaches the 9mm in capacity and the .45 in shootability. It’s all I ever carry anymore.
I’m with you wrt the 10mm cartridge. The mod 20 is also my platform of choice. It’s my standard winter / cold weather carry.
