The concept that a typical modern polystriker has improved safety features over an '80s or '90s era DA/SA auto is LAUGHABLE.
They also have no improvement in accuracy, reliability, or shootability (in fact are actually worse).
But, yes, they do have less parts, so good for them...
The Taurus G3 has all that a Glock has AND a frame mounted side safety, which I love...Just for giggles, watch the YouTube Sootch review video on the Taurus G3. It made a believer out of him.
IMO, the modern striker fired pistols do have a reliability edge on older DA/SA pistols. In a world of simplicity and cost versus precise and sometimes complicated effectiveness, the old DA/SA's like the S&W 39's and others series are heavy, complicated and dated compared to modern striker pistols.
Once again, complexity doesn't mean better...If that's the case, then why do no modern PD's carry S&W 59's, Colt Double Eagles and Beretta 92's anymore?... They are too complicated, too many machined parts to tend to, heavier, costlier and most of the time, more finicky. Also, the same reason the US military dropped Thompson SMG's in WW2 for M3 grease guns, and Germany dropped the lugers for P38's.
As I said before, modern 9mm striker fired pistols are the Model 10/Official Police guns
of our time....Plus, the 9mm round has come a LONG way ballistically in the last 20 years. That is why .40's have fallen from grace. The modern 9mm's do that same thing with less cost and recoil.
If classic designs were "better" by modern standards, then all PD's would go back to registered magnums.
