THE IMAGE ABOVE IS A PAID ADVERTISEMENT Is there any real advantage or disadvantage to putting in lighter mainspring springs in the p series DA/SA handguns? thanks |

It was a PITA but, I noticed a significant improvement when I swapped in a Wolff Mainspring into my P6

In the P6 it make a huge difference. I only put a 22lb in mine and it reduced the pull at least 4lbs and it seems smoother.
In my other P series Sigs, I've kept them factory. They're no where near as heavy as the P6 (obviously). |

In my view, there is no other single modification that you can do to a SIG that will affect trigger pull as much as changing the mainspring. I personally do not like a heavy trigger pull like that found on the P6. The more force you have to exert to operate the trigger, the less accurate you are. Therefore, I prefer a 4 to 4.5 lb. trigger pull weight. On most of my SIGs, I have switched to a 19 lb. mainspring with great results. YMMV.
The disadvantage to going to a lighter mainspring is the potential for light primer strikes. That is why most good gunsmiths do not recommend going below an 18 or 19 lb. mainspring. In any event, make sure you try various types of ammo at the range if you go to a lighter mainspring to ensure proper ignition. Good luck mate. |

I have 17 pound springs in all of my P-series pistols and have never had a light primer strike. Drastically improved DA trigger pulls in all of them. -Tac |

Since we're on the topic of mainsprings, does anyone know the factory weight of the P6 mainspring? 24 lbs?
I'd like to lighten up the DA pull a bit but don't want to induce light primer strikes. Though I do like the idea of a heavy DA pull for safety reasons, as it is one of my CCWs. |

I recall reading somewhere that P225's had a 24 lbs mainspring and the P6 had a 28 lbs mainspring. I replaced the factory spring on my P6 with a Wolff 20 lbs spring; I originally tried the 18 & 19 lbs springs but had too many failures to fire even with repeated trigger pulls. |

I had the exact same experience with my P6. The 20 lb. spring works for me as well. |
