For many years it was a .357 magnum revolver...I cc'd a 2.25" Ruger SP101 in .357 magnum for nearly 10 years.

Then I switched to 357SIG and carried a Glock 33 for about 7 years.

Since 2012, it's been the .45 acp...which is still probably my favorite overall CC caliber...but lately I've been playing around with .45 Colt round...which, in +P format...is quite a hoot to shoot!
