Nothing gun related but for me it’s either .45 or 9mm. I just don’t like the way a .40 recoils. Guess it’s too much of a snap where the 9mm is a pop and .45 is a push.
I do have a 9C, 45C, and a 9FS (it’ll be here on Wednesday) that have been mostly trouble free through a combined 35K rounds, although I’ve developed a dead trigger in the 9C that Apex is taking care of and a failure to fire that hopefully a new striker will fix.
Buying a gun to cure “boring” is treating the symptom, not the disease.
“Boring” is a whole other set of problems, none of which can be solved by a caliber switch.
If you are using this for HD, then “boring” should not be a considration. The best handguns I own are “boring”: they put the bullet where I want it to go and go ‘bang’ everytime. So, Im not really sure why this would be a consideration.
Having said that, here some more practical things to consider:
[ul]
9mm is cheaper
9mm holds more rounds
9mm has less recoil
[/ul]
[ul]
40 has better barrier penetration
40 has larger expansion (lets not into a debate)
40 can be converted to .357 sig or 9mm with a conversion kit[/ul]
There is no universal right answer, only the one that is right for YOU. Food for thought.
