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.

Incredible job taking a confusing subject, often plagued by inaccurate information, and making the topic easy to understand. I now feel better equipped to tune my guns, thanks!
I'm so glad it was helpful! Thanks so much for the great feedback. Thats exactly what I was hoping to acheive.
Good whiteboard breakdown. Easy to follow. Thanks!
I love your channel. Keep going! Your content is amazing.
Extremely under-rated and under the radar channel. Awesome content. Been binging your catalog of videos lately. Keep em coming.
Thanks so much! The kind words mean a lot to me. I'm glad you're enjoying the content - I plan on continuing to make it!
Excellent job thank you so much
Appreciated this upload! Getting ready to assess my Obsidian 45 on some .45, 10mm and 9mm pistols. Springs will absolutely come into play. Thanks much
You're most welcome! I hope its helpful. I would be curious to hear what you find regarding spring weight as it relates to suppressor use. I have had a mixed bag of results myself. Some like lighter springs, some like heavier.
Loved the energy analysis! i think that it can take into consideration the energy lost as friction during the bullet's travel through the barrel, something that the more frequently encountered conservation of momentum analysis can not do.
Thank you! Its always made the most sense to me that way!
The white board is the most re-markable invention!
HA! Good one Dad!
Hell yeah love it! Thanks for the video!
Just wanted to say I really enjoy this channel keep it up man
Really appreciate that man! Thank you!
Very cool😎
I know you have a couple M90 videos if your gas tube front handguard retainer came loose how would you go about fixing

Heck yeah, let me know if its useful information!
Hello D , when tuning hammer fired guns ex czp09 .. please help explain how the hammer spring rate affects the initial barrel un lock and recoil impulse and muzzle flip ?
A heavier hammer spring will require more force to initially push back down while the slide starts traveling rearward and the barrel is unlocking. It may increase force required for the action to unlock, but the recoil spring controls the relationship of the slide to barrel and the actual unlocking action. In terms of overall recoil impulse and muzzle flip it shouldn't have any affect becuase when the hammer is in the fully cocked position it puts very little upward force on the bottom of the slide as it passes over the top.
I have heard wildly different ideas about how the mainspring affects recoil. I have heard that if you change recoil spring weight you should also change mainspring weight to keep the "overall spring force" and "timing" of the barrel unlocking the same. I have also heard that it doesn't matter at all. Select a main spring that gives you the trigger feel and reliability of ignition you want, and tune the recoil spring based on ejection distance and feel.
In my experience I agree more with the second idea. I put in whatever mainspring I want for my desired trigger action, then tune the recoil spring to my normal ammo and the ejection distance I want. I don't worry at all or consider how the mainspring affects my recoil impulse, the barrel unlocking, or ejection pattern.
Great question! I'm no expert and thats just my thoughts based on my experience. Hope it helps!
Here is a link to my favorite recoil spring tuning guide:
cajungunworks.com/how-to-select-the-proper-recoil-spring/
I have installed on my P10F Toni System 12 lb recoil spring end steel guide rod ( i guess the factory spring is 16lb) . It seems better shooter now (softer recoil). How do you see it in theory? Factory ammo S&B 124gr.
Lighter spring will increase slide velocity. I would expect ejection distance to increase. I would expect a little more snap as the slide comes rearward. The increased slide velocity means it will hit the rear of its travel harder, also leading to more muzzle flip. The slide will come back into battery softer with the lighter spring so I would expect less muzzle dip and a quicker return of the muzzle on target. There is a big part of recoil feel that is subjective. What feels better/softer to you may not to the next person.
Thanks for watching and commenting!
@@dltz thank you! 👍🏻
