Malpaso, I have two Browning .40 HP's. One is the standard MKIII the other is a practical. The only thing that has been done to the triggers on both is removing the mag safety. The Practical has had over 4,000 rounds of my reloads through it and the trigger is in the area of 4 lbs. and crisp. The MarkIII has not been shot that much and the trigger is over 6 lbs. The Practical has Heinie sights that have a picture not unlike the Bowmars. The MarkIII wears Novacs. I have replaced the 20 lb. factory recoil spring in the Practical with a wolff 18.5 lb spring. Since all my reloads are running around 930 FPS I have no problem with the lighter spring. You could try a Sprinco recoil reducer. It makes assembly much easier but I could not tell any difference with it in the gun other than the ejected brass went more to the side than to the rear. I also think the lock time was too short with the Sprinco unit. If you are looking for a gun smith to work on your HP, I might suggest Ross Carter in Harrison Arkansas. His work is first rate and 100% guaranted. The mag you got with the gun is factory if it has the external spring. After market mags made by Mecgar are very relilable in my guns. They also make the factory mags.
I am heading for the Chapman Academy of Practical Shooting this Sunday (Oct. 1). Will probably put another 1,800 rounds or more through the Practical. Five day course, eight hours a day. Shoot Safe.....CO
