Clean out the factory grease from the striker channel before firing the first time. Put 250 rounds through it for break-in. If you plan on carrying with safety practice flicking the safety off when drawing.
I have the SR9 and SR9C and love shooting both. Very accurate guns. Don't ride the slide when chambering a round. Sling shot it! Galloway Precision makes good after market performance parts. The trigger is awesome with a very clean break and reset. The more you shoot it the better the trigger will feel.
