Pistol Recoil Spring Tuning

Описание: DISCLAIMER: I am in no way encouraging or advising anyone viewing this video to attempt to modify their firearms. I am NOT a professional gunsmith! If you are not 100% confident in your ability to modify firearm components AND well experienced, DO NOT even attempt it! Always seek a professional gunsmith if there is any doubt!

I discuss pistol recoil spring tuning. Specifically pistols with Browning action tilting barrels. I will give some general guidelines, then give some engineering focused explanation with the help of my trusty white board. Then I show how I selected a recoil spring for a specific pistol I wanted to tune.
