Taurus
PT709 new ATS sights (and the grip extension review below.)
Yellow front sights, orange rear, except on the Taurus, I thought I'll try green rear a while, I'm sure I'll probably switch to orange rear later, I like the yellow front, orange rear, always have. Works well no matter what color shirt a target has on, and well in low light/backlit I still can make a triangle/pyramid.
My camera flash doesn't do the sight colors justice, I'm not a photographer.
Now any of these can easily be operated with only one hand
(I was about to sell the Taurus for that reason, until I got these sights)
The Taurus slide is easy to rack now, much safer for me to operate than it was with the cheap plastic factory sights.
And making the triangle/pyramid (sight picture) or finding the front sight ... is fast...
These sights have
multiple angles in their design, hard to describe but ...
Top photo, note the angles on the rear sights, these don't dig into my side like square sights did. Much more comfortable, less likely than Novak "snagless" sights to snag while drawing due to the slopes (see bottom photo).

The very
center of the rear sight's pyramid is taller to allow one-hand slide operation by racking on a belt/holster/shoe etc., yet angled so as not to unintentionally snag on anything ... as I said, hard to describe, easy to understand when using them
Bottom photo On the Taurus you can see (sorta) the angle of the green rear sight is less likely to snag when drawing now (my pocket holster has a seam the old sights would snag it, these don't because of the slant/angle)
First day impression on the extra long Garrison Grip extensions on the Taurus PT709 went on easily, and let my whole hand get a grip; they also seem to hold the pistol in upright position in my pocket holster better; beats the beejeebers out of the
tiny Keltec PF9 type finger extension.
