No it is not adjustable, per say. S&W sells a MA state 10 pound trigger pull on all models. You would have to special order that model, as it normally is only sold in MA. You would be the exception, as most want a lower trigger pull pressure, not higher. The gun is safe and even at the 6.5 pounds stock pull, the gun is not going to get accidentially fired. Your finger has to pull the trigger back to get the gun to fire. There are trigger kits available that make the break more crisp, shorten the reset, and spring combinations to change the stock pull of 6.5 pound to 5, 4, and 3 pounds pull. I can only speculate you are new to handguns and are worrird about accidential firing. The guns are designed to be safe and accidental firing are a result of unsafe gun handling, not due to low trigger pull pressure.
