Haven't seen the part number or at any other online retailers. I guess I'll need to call Sig direct.


Stemming from finally my first real quality time spent with my new P320 setup. (1000 rnds over a single day of shooting).

Not really a big deal but my takedown lever is a smidge irritating on my left hand right about my thumb joint.

2 of my 4  17 rnd magazines will finally function at full capacity. Now if the other 2 will get with the program

Have about 1500-1900 rounds through it total.

Call them.  If you register the gun with Sig, you get a discount code on your order from them.

Why are your mags not working??

If you tried to load 17+1 in the chamber, the magazine would fit really tight and the 1st round would shortstroke due to the tension.

My gen 2 ex G17 had a few mags that would not go to 17. Ancient history now but it happens.

I had to call Sig direct for my new flat take down lever myself. Don't forget to order the O ring with it. I have an extra to spare if you're interested.
