All three are perfectly good guns. Good enough that you're getting into personal preference territory. And accuracy is pretty much an operator function among these three. As you've just seen, one guy likes glocks best, one sig. Pretty soon someone will mention beretta's being used by the military... and on and on. I'd go to a shop and fondle all three. See which "fits" your hand best. Then see if you can shoot your two favorites with a friend or seven, or maybe rent 'em at a range. I do have a decided favorite among the three, but it's not really relevant to your own search.
Cant go wrong with any of those three. All are great and it is just personal preference. Myself, I like Glocks, but they are not for everyone. Sigs are excellent guns, but they just do not feel right in my hand no matter how hard I try. Beretta 92 feels really nice in my hand. To each his own. Good luck with your decision.
whats the honest, unbiased comparison of the Beretta 92 with the Glock or Sig 9mm pistols.
whats the accuracy difference?
Objectively:
Any one of them is as dependable and reliable as the others.
The Beretta and the Sig are more accurate than the Glock. I get better accuracy from the Beretta, but that may well be because the gun fits me better. The Glock is more than adequate
The Glock MAY withstand abuse better than the others. But any of the three will withstand hard, sane, use as well as the others. So long as you don't feel an urge to drag your gun behind your truck, this is a draw.
There are Sigs and Glocks available which are smaller and easier to conceal than the Berettas. The Beretta can be concealed, but it takes work and proper attention to dress. Even the no longer made compact Berettas suffered from this affliction.
Subjectively
The Beretta feels best in the hand to me. It sits lower in the hand than the Sig, and quicker recovery between shots. The Glock doesn't feel right in my hand, and doesn't point well.
I think the Beretta is smoother overall to operate, but the Sig's double action trigger is a thing of beauty.
The Beretta is the best looking of the bunch. Fans of the others may disagree. But they are wrong
All three are quality firearms and the parts are easy to find. Beretta's customer service on the other hand is very usless to the common person. They are too quick to blow you off.
"Expand your vocabulary. Having a wider knowledge of words that you have at your disposal is amazingly useful, and makes you seem more tolerant and intelligent to the casual observer or audience. Buy yourself a thesaurus or research on the internet for synonyms of words that you would want to use as alternatives to gay."I could give you the same boring response everyone does "they are all good, get one and practice with it. you can't go wrong with any of those." But thats gay.
Get a Glock!
