Pistol Recoil Spring Tuning

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. ‪@TheHumbleMarksman‬ Has some good videos about this:    • Which ammo makes compensated guns shoot fl...      • How to Tune Your Recoil Spring - On a Gloc...   ‪@AtlasGunworks‬ Has a good video:    • Recoil Spring Tuning v2, Atlas Gunworks   Two web pages I found helpful: https://pistolwizard.com/guides/recoi... https://cajungunworks.com/how-to-sele... 00:00 Intro 01:39 General rules of thumb introduction 02:37 Fuction, reliability 02:58 Cartridge power 03:26 Direct blowback vs locked breach 04:00 Slide length and mass 04:29 Compensators and ported barrels 04:36 Muzzle flip and dive 05:06 Slide velocity & ejection distance 05:26 Cycling issues 06:26 Suppressor use 08:32 Spring preload 10:56 Spring life 11:25 In depth explanation introduction 11:55 Energy, mass, velocity 13:12 Velocity is a vector! 14:04 Barrel and slide moving together 14:35 Breach unlocking energy 16:03 Initial velocity, equal and opposite forces 16:39 Slide at the rear of its travel 17:02 Spring pushing slide forward, feeding issues, muzzle dip 17:59 Muzzle flip and felt recoil 18:19 Barrel porting and compensators 21:34 Tuning and testing on my pistol intro 23:09 Slow motion footage, muzzle flip and dip comparison 25:37 Ejection distance comparison 26:10 Final spring choice 26:30 Conclusion and wrap up
