Your mileage may and probably will, vary greatly.
I have one Sig, the P238, which is a damn well made gun.
It feels good in the hand, points well, shoots consistently to point of aim, regardless of ammo, but it was a little pricey for a .380...especially when one considers my EDC is a .380 that I paid less than $220.00 for and it does everything the Sig does for nearly $500.00 less.
I will grant that the Sig will probably endure 100,000 rounds, whereas the Bersa may not go 50,000, but I'm hoping like hell I don't have THAT may bad guys coming for me.
Anyway, S&W was the only other submitter, so by almost default, it went to Sig, mainly because they filled the specs better than S&W.
It was rumored that no one else even submitted...not wishing to endure the political silliness that a new weapon system engenders, making the whole process drag out to several years.
And even though it is manufactured in New Hampshire, with American workers being paid to build it, it is first and foremost, a foreign company.
The best I can say is that it fills the need.
It's just unfortunate that the powers that are thinks they have this recurring need every career cycle.
850 million dollars for a handgun contract ain't peanuts.
It makes no sense to me for our boys to carry German pistols. We need only to update the 1911 and keep that trigger like it is. Just adapt them to a double-stack mag holding 15 rounds and thread the muzzle to accept stuff. That’s ALL that needs doing, and it’d be hundreds of millions cheaper. Also, I prefer 9mm to .45. More velocity, cheaper rounds, more bullets in the same amount of mag space, reduced muzzle flip, faster follow ups, hollows open up to .452” upon contact, ammo’s lighter, I can go on all day about why the 9mm is superior, but the best thing about the 1911 and where it truly rises above other pistols is that sweet, single-action trigger.
Nope, S&W (M&P), FN, KRISS, Glock (finalist) and Beretta were all in as was Springfield Armory.
The P320 is a terrific choice and is truly modular. i found the ergonomics to be first rate.
