Several years ago I pick up a used SW40VE to use as a range gun and I liked how the gun fit in my hand. The gun had a heavy gritty trigger. But we know that is nothing new when it comes to a Sigma. Did some polishing of trigger parts, dropped the pigtail spring and it help some. But the trigger pull was still heavy, around eight to ten pounds. Never broke the same each time I pulled the trigger. The gun never gave me any problems, just never broke the same each time. After reading about the trigger springs kits I order a Galloway spring set. Dropped it in and did some more polishing on different trigger parts. What a different the spring kit made along with the polishing. The gun is breaking around six pounds on my old trigger pull gauge. Good clean breaks each time and no problems. But the real test will be with some of my reloads and Tula/Wolf primers. If the gun will fire my reloads with the Tula/Wolf primers then it will get upgraded to a truck gun. But it will not replace my Glock 23 as my carry gun. All in all the spring kit was worth the money.
