generally i like the beretta better. i like the 92fs with the angled dust cover and no rail,the slightly deeper radius cut for the webbing of the hand,the forward flared bottom on the front strap,plus the option of other beretta 90 series family(evolution if you prefer) to choose from and they all come stock(current models NIB) with the latest beretta falling block. overall the berettas have been forced to go through a bit more "hell",forced to listen to it's main users a bit more and come out the other end a bit better for it.
not all new berettas come with everything above though,you have to know what you want and get it.
i've kinda always prefered the safety/decocker of the taurus on the frame but as time(years really) has gone by,i see it less and less of an issue and it's not a deciding factor for me any more.
i do think that in black the beretta has a better,more durable finish but you can always go with the taurus stainless look,..although,the stainless on the taurus can have a strange rainbow effect that i don't like,some taurus stainless don't have this but you have to look for them. i'm sure you can find an AFS. of course,there's the 92fs INOX.
the newer 917 have finger grooves,bit shorter barrel/slide and dove-tailed front sight and they can come stock with fiber optic front. i was disappointed when the 917 disappeared from their site but you can still find them. i actually like this one over at least some berettas and it comes in black or stainless. the features on this one just seem to come together nicely.
i like the fact you can get pt99 with adj rear that doesn't cost much more but i wouldn't go into enduring harms way with those,shouldn't be an issue otherwise. great factory NIB option and one up on beretta for this.
i'm not a brand snob when it comes to either one but long story short,neither one are losers,both are great but the scale tips towards beretta for me.
if you like the taurus,go for it. absolutely nothing wrong with it and you don't need to like what i like. other taurus models may be popular to many people and may have had no problems but the pt92 series has been a shining star in the taurus catalog for a long time now and unlike some other taurus models,refuses to go away. the gold colored controls option look gaudy to me but another factory option if you like.
sorry i discussed the beretta but i like both. both should be reliable.
