All dozen + SIG Classic P series pistols of mine have the twisted strand recoil springs in them since day one & will ONLY have the designated springs installed.

In 30+ years I have not had any issues with feeding/extraction,ejection,failing to fire in +90 to -50 degreeF temperatures in the Arctic.

I slap a set of Hogue rubber grip panels on each & run them like the German Engineered COMBAT pistol as they were designed.

Tupperware or other manufacturers pistols may operate better w/ progressive or overrated
+ spring rates.....
I wouldn't bet my life on either.....my SIG's work....ALL THE TIME.

K.I.S.S. Keep It Simple Stupid

IF,it ain't broke,don't attempt to fix it!!

I believe wolff is the one making the triple coiled recoil springs of SIG. I'm not quite sure, but heard it somewhere here. It'll run flawlessly on stock, but I also am interested in learning if someone every fine tuned their ammo to their springs, especially in the competition setting.

Doubtful, more than likely, a European source, as they have been doing it for decades.

I realize that going to a lighter spring may seem a smart move, but it allows the barrel to unlock sooner, and may cause sticky extraction issues, by not giving the brass time to shrink from expansion during firing. It can also allow some frame/locking insert battering, if too light.

GGI has a slightly heavier spring, I believe "pink" for +P 9mm use, which is lighter than the green spring of the .357/.40/.45 persuasion.

Yep, I found the pink springs to be too stiff for normal power factor loads, it's not gonna work well too with "cycle" loads.

I'm most likely going to go original weight springs, just was curious if there are people that changed weights or even if they went with the wolff alternative with the same weight and to see how that one compared to the OEM spring (which I believe to be also triple braided but without the orange paint).

Gerry R, stated that he sometimes went lighter on a clients weapon to enhance reliability. That may be fine and dandy, as long as heavier loads aren't used with the lighter springs. Start a pound lower, and see how it fares, Wolff has "Calibration Paks" from 10# to 14#. It has been theorized that empty ejection should be about 6 feet, IIRC from a standing position. That was from back in the day with Bullseye competition, so your empties wouldn't bother the competitor to your right.

Hmm, the calibration packs do seem tempting and it'll probably be the only "trial and error" option available. The only problem would just be finding the right balance between keeping frames from getting battered too hard and trying to keep that muzzle flip to a minimum while probably enhancing reliability. I don't really run lots of high pressure rounds, the highest would probably be just federal carry ammo, other than that it'd be the usual loads of FMJs and trying to meet the 125PF. Apart from those, cycle loads are typically lower at around 900+FPS for a 124gr.

Guess it's time to experiment unless someone already had and is willing to share their findings! :lol:
