I recently purchased a Blaser super trap after shooting a Guerini for some time. I like the design of the Baser and there weight system. It seemed I was all ways swinging over the target or past the target with the Guerini due to the light weight of the gun. Don't get me wrong the Guerini is a fine gun but not for me. My Scores were terrible. The Blaser weights about 8 lbs 14 oz out of the box. With there new weight system I was able to increase the weight to a little over 10 1/4 pounds. An even amount of weight must be added to front and back of the gun to balance it. How well did it work ?. You be the judge. Average score before on 16 yard with Guerini was 78.88. Now 91.00. Handicap 74.60. Now 88.00. The extra weight and balance seems to slow my swing down and I make smoother swings to the target. Hope it continues. Good shooting. P.s. The release triggers were put in by Pat McCarthy and are outstanding and adjustable. My unsingle is set at 80/20 .
