I have a CZ75 SP-01 in 9mm I would take to war as my most trusted and accurate pistol because in most things placement is king.
Folks we have a winner!!!
We get into schoolyard quarrels about the best gun to carry, if there is ever such a thing. Or the best ammo to carry, which is debatable...ok somewhat.
But how many will look at one gun, no matter the make or caliber and trust their life with it? If you happen to have such a gun, that's the one to carry. Having confidence in your gun, with caliber and foremost reliability, will help you train better and smarter as you'll have less things to worry about. And in turn, you'll see your hits/accuracy improve.
I've trained people with $4,000 custom made 1911's to few hundred dollar Hi-Points and most everything in between. If your gun meets the above, then brush off what others say about it and pack it with pride.
