Went to the shooting range today and rented a Sig P320 and a Beretta 92FS. I didn't like the Sig much, sorry Sig fans, just didn't impress me at all. The Beretta on the other hand was VERY nice! Fit my hand just perfect and shot SO nice. Trigger was very good, and quite accurate too! (The Sig wasn't). This is the 2nd 92 I've rented at different ranges and they both were impressive. Is this common? Are all 92s so nice? I see they have 92FS, 92A1, and M9A1 models. What's the difference? Do they all have nice triggers? Which one should I buy?
