Hello, just saw your message dont know if you are still dealing with this problem or not but here is my .2c worth. I have shot 1 sr9 good gun but I still prefer my P345. Do you have the updated (post recall) trigger assembly? That could make a diferance but I dont know for sure. My advice is to dry fire unloaded or with snap caps, untill you are used to the trigger pull. With theP345 and posably your SR9 do NOT dry fire with out the mag instaled due to the mag disconect safty it could damage the gun
