    Question about recoil springs

    Does the following statement make sense?
    The heavier recoil spring also means that while the slide's recoiling, it's pressing harder back on the frame and on you.

    The slide hitting, when it comes back, so hard as to throw the brass 20 to 50 feet is another nice indicator that you're getting more of a slam to your hand when this occurs.

    I do not in the slightest dispute that others perceive no difference or no significant difference. That there IS no difference, though, or that no one would be affected by it, would be a different statement.

    Not sure but, it seems the heavier the spring, the less felt recoil, as the spring is absorbing more slide energy.

    THAT is what I'd think too. Yet some guy on the 1911forum says heavier recoil spring means heavier felt recoil. Weird.

    I guess if you get a heavy enough spring the gun might recoil more before the spring started to give.

    There is probably a point where a spring can be too heavy and the recoil will get heavier but from what I've heard a little heavier will lessen recoil. This is what I was told, I have no personal experience to back this up. Factory springs work great for me.

    Its right you also get more frame to slide battering with a heavy spring ... If you go from say 16# to 18# its not gonna make a big difference



    Reason they say more recoil with heavy spring is the gun is absorbing most of recoil trying to get the slide to move which is forcing the gun farther back into your hand.

    Heavier recoil springs slow reward momentum, increase forward momentum. Maybe that's what he meant.

    Heavier recoil springs mean brass flies less from the gun. If the brass is being thrown quite a ways from the gun, the spring should be heavier.

    A heavier spring will make the gun recoil more, not less. It will also keep the rearward momentum of the slide from battering the frame unduly than a weaker spring.

    Brass should not be traveling 20-50 feet from the gun, if it is, replace the recoil spring with a new one thats factory spec or put a heavier spring in the gun. The frame is taking a beating if the brass is being thrown that far.

    My thoughts are that unless you have done something really off the wall with either your pistol , or your reloads the action of a pistol is engineered by folks a lot smarter than me to function reliably with what strangly enough is called FACTORY WEIGHT SPRINGS any change from this is in all likelyhood not going to assist reliablility of a stock or even close to stock pistol with normal range ammo.

    Yes, you get more "impulse" back and forward, with a heavier spring. Really hot loads or sub-gun fodder really are the only variables that warrant much deviation from the factory#.

    A lighter spring, with modest loads will feels much smoother, and recover faster. Glockracing has an interesting FAQ note on this, in particular that (in his experience) Glocks are not guns to worry about frame damage with going "too light" (within reason, of course).

    Edit to add: recoil is subjective, but, in context, would you "feel" more recoil pushing a 124 gr 9mm 1400 FPS, and slamming the slide back and forth, or riding the pressure curve with the heavier spring (you feel more motion, but no jarring back-forward slamming)? Redneck is right, this is the province of hotrodders. ( ;

    Well, the original discussion I was in, was in reference to 10mm AP. So I suppose that might be considered a hotrod round, depending on the load of course.
