I recently purchased a lightly used Ruger p345 at the gunshow I took it to the range and shot 200 rd's with no jams except for 2 that failed to go into battery on the last rd in the mag but my issue is the accuracy it was all over the place with out explanation even when i was holding dead center and firing very slowly it would hit everywhere except the point of aim. My second issue is when I got home and cleaned it put it back together I noticed when I racked the slide back it would push the trigger bar down and after I let the slide down it would not come back up,but when I started pulling the trigger to dry fire the trigger bar would pop back up in place making a noticeable click sound it didnt do this before it seems like the trigger bar is out of place is this normal for this gun to do this??? Thanks for helping
