We got a small break in the weather this morning and I got out and put 100 rounds of 115gr Remington UMC through the SR9. It's all very stiff of course. I used the little mag loader they provide which was very thoughtful considering I couldn't get them loaded without it. I'm in NJ so I have the 10 round magazines with plastic extension. They're stiff but I'm leaving them loaded at home to try to loosen them up a little.
So in 100 rounds I had about 8 stove pipes. No particular pattern, and I'm thinking I should give it a few hundred rounds before I worry about stuff like that. After a pretty big adjustment to the rear sight elevation it was shooting accurately (for me). I've heard some complain about the size of the safety button- I thought it was fine. Other good points are:
In my hand it feels a lot like a light, single stack 1911
It is pretty accurate
It is light but balanced- the slide doesn't dominate the frame- might make a nice carry piece
The trigger feels good and smooth- I didn't think it would while dry firing, but with ammo it's good
VERY low recoil. I'm used to my Sig 2022 which is top heavy and has a lot more recoil.
Has a reversible backstrap that is convex from the factory. Reversed it is flat. I tried changing it but returned it to convex because with the backstrap reversed the grip felt too small in my hand.
I have fired Glocks, XDs, M&Ps, etc and was concerned about the striker fire trigger, but I was pleasantly surprised. I may want to get some work done on the trigger, but I'm just going to let it go and get used to it first.
Stovepipes aside, all in all I am pleasantly surprised by how smooth and easily the gun fires, and how easy it is to keep on target in rapid fire.
For a $450 pistol new, I recommend it highly.
