A much more effective safety would have been a grip safety,

John Browning got it right back in 1911. If it "ain't broke" don't fix it

[M1911A1]

I read somewhere that Browning added the grip safety on the M1911 because the Army wanted one, not because he thought it needed one.

His final great pistol design had no grip safety, but it was chambered for the piddling .380 Long. ;-)
