I have owned my Gen 2 G19 since 1991. Never did any modifications to it as it did everything asked of it without complaint or issue. I recently bought a Ruger 10/22 Sporter which I modified with the Kidd internals, including the trigger kit. The vast improvement on the trigger feel made me think that the Glock with a light pull would be great and I found the M*CARBO spring kit video on Youtube. This excellent video went into great detail on polishing the internals and installation of the kit to achieve a good result. The care and detail given to this tutorial convinced me the the $16.00 (with free shipping code), would be well-spent. The kit was received a day early and my son and I did the polishing and installation in a couple of hours without a hitch. I did use some additional 2000 grit sandpaper as my firing pin safety was really rough and needed a lot of work. The 2000 grit polished it up to a mirror finish without taking off excess metal. I don't have a trigger pull gauge, but it is obvious that the trigger feel is lighter and smoother. Accuracy has improved as I am no longer fighting the heavy pull to hold the gun steady. It is no match trigger, but for me it has increased my enjoyment of the gun even after all these years. I can recommend this modification to anyone who has the time and patience to do the work needed. The tutorial will show you how in great detail. Thanks M*CARBO!

Purchased this kit for my 43. Polished all contact points and installed the 4lb spring. Reduced the pull from 5.5 lbs down to 3.5 lbs. Great product and fantastic results for about 30 minutes worth of work.

You guys are the best! I have been a 1911 man since graduating from Parris Island in 1972, got my first Glock and did not know which end was up. You hour plus video that showed me how install your spring kit and polish the parts was the nuts, and yes, the trigger pull is now smooth and just about cut in half as advertised!

Thanks Brothers!!
