The Smith and Wesson 638 airweight .38Spl with Crimson Trace grips is about the perfect concealed carry revolver. The lightweight aluminum frame paired with a steel cylinder and barrel balances out the S&W 638 to handle and shoot like a dream. While most shooters prefer a hammerless revolver for concealed carry, there are still those who want the option to pre-cock the hammer for a lighter single action trigger pull. The Smith & Wesson 638 has a concealed hammer spur that is still tactile enough to manipulate while still being snag free for concealed carry. The largest drawback of small compact revolvers is that the sights can be hard to see and given the design are typically machined into the frame/barrel so changing them is almost impossible. This is where the Crimson Trace lasergrips on the S&W 638 .38Spl really shine, a simple replacement grip unit that has a single activation button located along the front strap of the grip for instictive activation. The Crimson Trace laser grip is full adjustable for windage and elevation allowing shooters to dial in their S&W 638 for precise shot placement from any angle or position.
