I love my S&W 40. But the only thing i don't like is the trigger it takes way to much pressure to make it Fire to me & is throwing off my accuracy is there any good & on the cheaper side triggers for this gun ?
Polish the side of the trigger bar that rubs on the plastic frame, then clean it and put in some grease.
Then be sure the safety blocker, the round piston moved by the front prong of the trigger bar, is well lubed, again with grease.
Now, work on your grip. Be sure the grip is well-seated in the web of your thumb and your hand is well up on the grip. Grip with your trigger hand as if someone is trying to take the gun from you but keep your trigger finger completely relaxed and lying along the outside of the trigger guard, just parallel to, but below, the slide. Then use your other hand to envelope yur trigger hand with the thumb pointing forward on the frame. Your trigger finger should play no part in holding the gun, NONE.
Now, with that firm grip, use your trigger finger to squeeze the trigger while it plays absolutely no part in holding the gun. Dry fire in a safe place until you can pull the trigger without disturbing your aim.
Once you can squeeze the trigger without changing the aiming point, try relaxing a bit from the white-knuckle grip and practice until it becomes a natural process. The white-knuckle grip must go away or it will cause your hands to shake. Ignore the slight take-up at the start of trigger movement, it's just the trigger bar moving to contact the sear, just part of the design.
Remember, your two hands hold the gun, the trigger finger just squeezes the trigger.
