Absolutely amazing - Volquartsen Firearms Ruger Mark IV Pistol Competition Kit

I do have to admit I have not shot it yet but. Before installing the new firing pin I did a bunch of dry fire to set the new pre and post travel on the trigger. And it is night and day. Very little take up. And crisp clean break and very nice tactile reset. The video link provided in the instructions made it a breeze to install. All the the parts are perfectly machined and just look overall well made and a drastic improvement over stock. Highly recommended
