I am carrying mine right now. I love it! At first, I thought it would be just like every other Ruger (except for the Mark series) I had used before. But, after examining it, I was taken by its simplicity and quality. It now has over 500 rounds through it without one single hitch. After trying out the different back strap positions, I prefer the arched side as to the flat side.
As of right now, it is one of the most accurate 9mm's I own. (my EMP is pretty darn accurate) I think its shootability is due to its low bore axis and good balance. The one thing I would add to it if I could would be a grip safety in addition to its well placed 1911 style thumb safety. Grip safeties make me feel ubber safe when carrying locked and loaded.
The only problem I have had is that the front sight is so tall, it often snags on my holster. I think that this problem can be solved by switching to a poly paddle holster or something similar. Does anybody have any suggestions for a good holster for the SR9?
Lastly, even though the front sight is so tall, I still like the sights, but wish I could night sights for it. Does anyone know of a manufacturer that makes tritrium sights for it?
