anybody tried LC9 recoil springs in LC380 ?

has anybody tried using the LC9 recoil springs in the LC380 ?

I really like the LC380 and so far have the galloway trigger kit installed (awesome) and their steel guide rod which weighs 9g vs plastic 2g so that should reduce recoil a small amount

now I'm going to try swapping 1 or 2 of the LC380 recoil springs with the LC9 recoil springs for less recoil

galloway sells a 20lb recoil spring for LC9 and says the factory recoil spring is rated at 16lb

since the 9mm is about twice the recoil pow factor of the 380 I'm guessing the LC380 factory recoil spring is somewhere around 8-10lb. Does anybody know for sure or have some tool to measure it ?

anyway those those springs are cheap $4 for both and I will try swapping 1 or the other at the range to see how some basic 95gr fmj ball ammo shoots. clearly swapping both springs likely would not work at all, but swapping 1 of the 2 springs should work

this will take a few weeks, I'll post the results

Less recoil in a LC380? why? It hardly has any now. I never mess with after market springs. Go with what the Engineers at Ruger designed for the gun.

well pal either pray it never happens to you or wait until your hands get arthritis and then tell me that LC380 doesn't have much recoil

as for the ruger engineers big woop they aren't shooting the gun I am, see the difference ?

this place makes all kinds of springs notice the +/- 1,2,3 lb ratings from factory springs for peeps who want to tailor recoil for the ammo etc

I will be interested to hear the results. I ordered wolff springs for mine.

I'll be interested also. Could make the slide really hard to rack.

Correct me if incorrect but, a recoil spring is used to dampen the effect of recoil caused by the power of a given cartridge thus affecting the cycle rate of the pistol. In other words, a higher power cartridge needs a heavier recoil spring while a lesser powered cartridge would not need a heavy spring to cycle the action. A heavy recoil spring would therefore cause the action not to cycle properly on a cartridge like the .380. An example of this would standard velocity .22LR ammo failing to cycle some .22 autos.

ok

i think what you typed is accurate but missing something about the range of spring rates that will properly cycle for a specific cartridge

ex: when brand X 95gr fmj ball fires it pushes out the bullet at 940 fps this recoil energy in the LC380 can properly cycle a range a recoil spring ratings from 8lbs up to 14lbs (just guessing at the numbers)

by properly cycle I mean the spent cartridge will be ejected when the slide moves back and a fresh cartridge will be stripped from the magazine and pushed into the chamber when the slide moves forward

for an 8lb spring the slide velocity moving back & forward after firing the cartridge is faster than the 14lb spring, this faster slide velocity is what the person holding the gun feels in the grip as the slide slams back/forth

because clearly if what I typed is incorrect then galloway would not be able to sell a 20lb recoil spring for 9m when the factory recoil spring is rated at 16lb, that is a 25% increase and yet galloway claims on their website the recoil spring will function fine with basic ball ammo - plus this just seems like physics stuff, force moving mass etc

since the ruger lc380 & lc9 are both dual recoil springs, i'm guessing that if i just try replacing 1 or the other instead of both, this will be some reduced value - whatever I will try this & see what happens
