I got an SR9. I shot it off bench rest at 15 yards. It shot a 2 inch group out of 6 shots. I noticed the trigger pull is horrible (like so many semi autos). There is the creep then more creep then a third creep then boom. I really took my time and the gun shoots pretty good but if triggger pull could be improved I think this could be a very accurate pistol.Can the trigger pull be refined easily???
