After reading the magazine articles about how wonderful the new SR9, I begain to wonder if there was something wrong with mine because my trigger was the pits.
I tried someone elses trick of removing the magazine disconnector in the slide, but noticed no difference. What mine felt like was a gritty 2 stage trigger with a long take-up.
Internally, the SR9 looks like a Glock with the addition of a spring that pushes up on the rear of the trigger-bar. So, I went through the normal steps that I would go through to polish the surfaces on a new Glock. Still no good.
After closer examination it became apparent that the trigger bar was rubbing up against the frame of the pistol as the trigger was being pulled. I could see the rear of the trigger bar moving to the right side of the gun. Looking at the connector I could see that the angle at the base of the connector was causing the trigger bar to move out as the trigger was being pulled.
After several attempts to reform the angle at the base of the connector I got it so the top of the connector is about 1/2 the width of the trigger bar away from the bar on the safety.
The second change was to the polymer frame itself. As I ran my finger along the inside of the frame where the trigger bar was rubbing, I could feel some roughness left by the manufacturing process. I lightly sanded this until it was smooth.
The result is that I no longer have the hesitation as I pull the trigger, the gritty feeling is gone and what I'm left with is a long take-up, quite a bit of creep (with no gritty feeling in the creep), and a decent break.
If you have the same problem as I had, I recommend trying the sanding first and see if that resolves the problem without working on the connector.
Another word of caution: don't try to force the cam-block retaining pins into the frame. After disassembly/reassembly half-dozen times I had a little trouble putting in the upper pin so I hit it with a hammer. Turns out the cam-block retaining spring had slipped out of place and I really mangled it. Patience? I don't have any patients - I'm not a doctor.

! Totally unuseable. It was even worse than the Turdus 94 I used to have. Looooots of creep. And maybe their is some Gritty Kitty Litter in there too. To call it a two stage is being polite. It runs into what feels like a boulder in the mechanism, and you have to apply significant pressure to finally get it to break. I bet I couldn't hit the broadside of a barn from inside in it's present state.
