I purchased a p320 x vtac a few mints back and I’ve been working on upgrading it to what I like. I’ve put on the skeleton flag trigger, 20% less sear spring, and a Wilson combat grip module. I love the gun itself… but the sights are terrible. After reading the reviews and seeing the features on the holosun 507c x2 I’ve decided for that to be the red dot I want. I cannot for the life of me figure out what adapter plate I need for the optic mounting with all of the options and websites being quite confusing. Any help would be greatly appreciated!

There is a phone number on their site. They have always been very helpful along with making a great product.

I will try that thank you!

Sig has done no favors in having five different optic cuts in five years. The most recent "R2" cut has screw holes for the R1P/DPP and the RMR footprint optics, however a filler plate (available from C&H) is recommended to brace the optic in place laterally.

Welcome to the forum, by the way. You might check out the classifieds for Sigforum member pricing on Holosun...

No kidding it’s been a mess trying to get an exact spec for my gun. Thanks for the info on the filler plate and the classifieds section I will definitely be looking into both!

Bobro Engineering makes a good adapter and sight combo. The 507 is the same footprint as the RMR.

Everything I've ever seen from CHPWS is junk. Bad fit, machine marks, you name it. Utter trash.

The best P320 adapter plates are made by Forward Controls Design. I'm not sure if the VTAC has the R1 or R1P cut, so that needs to be confirmed.

Holosun has a new 320 SCS direct mount coming out soon. Probably the best option:

IMO, these direct mount options from Holosun are going to force other optic manufactures to come out with competing products.
