Why The Different Hammers?

[progun1]

Hello all,
I am considering a P64 to join the other 9x18's. Why are there two different hammer styles, loop and spur? Are they separated by years made? Thank you.

Round ones are earlier and triangle are later models.

I think they changed to the triangle ones to make thumb cocking easier. With mine it's easy to thumb cock it while drawing, to avoid that stiff DA trigger pull. Mine's a '73 model, so the triangle ones came in before then.

My 1971 model is rounded while my 1977 is a triangle. i prefer the rounded trigger as it has proven to be snag free.
