Sig P320 Flat Trigger vs. Curved

The flat-faced Sig P320 Apex trigger is specifically designed for the upgraded version of the Sig Sauer P320. The flat design of this trigger enables the shooter to take advantage of the increased leverage by engaging the lower finger on the face of the trigger. Choosing between a flat trigger or a curved trigger is a matter of personal preference.

Apex Sig P320 Trigger Is Easy To Install

The Apex flat trigger P320 for the Sig Sauer P320 is easy to install without any special parts and does not require a gunsmith. The drop-in design of the P320 trigger makes it ideal for those looking for a quick and easy alternative to the factory curved trigger. The installment of this trigger will not change the trigger pull weight. The trigger is manufactured to meet factory drop safety specifications and will not alter the function of your pistol. Keep in mind that the Apex flat trigger P320 replacement will only work with upgraded Sig Sauer P320 models. The Sig P320 Apex trigger will not work with non-factory upgraded P320 models and will not fit the Sig Sauer P250 model.

    What a difference! I recently got a Mantis X3 for practicing trigger pull on my P320, and I was scoring in the 70's and 80' my first time using it. I put the Apex trigger in 2 days later and used the Mantis again...average is now in the low 90's. I need to get to the range and try, but I have a feeling it will definitely improve live fire as well. Well worth the upgrade!
