A fantastic upgrade for my Ruger MkIV 22/45, just a tad difficult to install but well worth the money. Thank you for a great product.

Nice upgrade Kit for my Mark 4 Lite
I bought this kit since I like to customize my pistols. Thanks to the detailed instructions in the videos the installation was very easy and didn't take a lot of time.

Good upgrade over stock about 3 1/2lb pull but I live a very light trigger.

Ultimate Trigger Kit for Ruger MKIV 22/45
Reasonably easy to install, just go along with the video and take your time. Very well made, the machnining is perfect. The factory trigger on the MKIV 22/45 is marginally acceptable at best. This kit changes all that. Beautiful trigger pull. Light, crisp and precise. I like the shield for the hammer and sear. Makes a big difference in keeping the internals of the pistol clean. The flat trigger and its adjustability enhances the trigger action even more. 100% recommend this if you're looking to drastically improve your trigger.

Ultimate" Trigger Kit for Ruger® MKIV 22/45
I had this kit installed on my Ruger 22/45 tactical. The trigger is absolutely awesome. improved the accuracy of hits by a large margin compared to the stock trigger. I also had the titanium firing pin and claw extractor installed. I highly recommend these parts.

This kit is hands down the best improvement I ve made on my Mark IV. Read TK s article about pre and post travel screws before installation.
