Great product. Install took a bit.
I watched the install video, and everything was great except the sear spring. It’s just a little hard to see that the long leg of the spring goes into the grip slot. Also, I had to set the hammer to get the safety to align properly. I am definitely not a gunsmith. Great trigger! Once I adjusted it to my liking, I was drilling holes in my target. Way better than the stock trigger!

Ultimate Trigger Kit for Ruger® Mark IV Worthwhile Investment
If you are doing competitive shooting this trigger improvement is a must. Hard to believe Ruger would fall down so badly on a "Target" pistol by give the user a 5 lb. pull and a mile of pretravel before the sear breaks. Now I have a 2 lb. pull and full adjustability for pretravel. I used it for the first time last night in our local pistol league and my score improved in all 3 categories. Bravo! Installation was easy for me but I can see how some people may need professional help. Tandemkross, Loctite does sell small one time use packets of their thread locking compounds. You would be great people to include one with this kit. They can't cost much in bulk.

Ultimate Trigger Kit for Ruger Mark IV
I installed the trigger kit myself and I am very happy with the results. My accuracy has improved greatly. The installation is a little tricky however. Unless you have a lot of patience and good manual dexterity, I would suggest you have a professional do it.

Ultimate trigger kit
Did exactly what I was hoping for. Lightened my trigger pull to roughly 2 pounds. Cleared up my tendency to pull low left. Also lowered my time in my local steel challenge shoots. Could not be happier.

Required update makes big difference
I did not like the trigger from the start that came with the 22/45. Pinched my finger first time I shot it, so that had to go. Once I saw how well engineered and manufatcured these were, I had to get it. Install was not as bad as I thought. The video is the best. The TK guy does a great job. It was installed and it works great. Shoots so smooth now, I can't blame my misses on that trigger now!

Great upgrade except for the set screws
Great upgrade from the factory trigger. Went from 5# to 3#. I love the magazine disconnect. I like that my gun has less moving parts now because this trigger allows some factory parts to be done away with. The only con I have is the set screws. Especially the reset screw. It just wasn’t something to be desired. But after making the proper adjustments on both the over pull and the reset screws the trigger feels great.
