Hello,

I am new to the 320. I have the FS version, with a medium frame. I would like to reduce the trigger reach a smidge.

Would changing to a Full Sized/Small frame reduce this reach as well as the thickness?

or is it just the grip area that is thinner?


Does Gray Guns' Hybrid upgrade reduce the reach in addition to all of the quality of use upgrades?

What about the Apex Forward Set trigger/bar upgrade?

I read 'flat trigger' and my first instinct is that it increases the reach. How wrong am I?

I had a trainee with very small hands that I had try the small grip module. She didn’t think it made enough difference and went back to the medium. I don’t have it available to try any measurements, though.

Depending on where one’s finger contacts the trigger, the straight trigger can reduce the reach distance. Again, I don’t have a curved trigger installed to check, but because it curves forward at the bottom and the straight trigger doesn’t, I find the straight trigger easier to reach because my finger curves toward the bottom of the trigger guard. That’s why I have straight triggers in all my striker fire SIGs.

Try the xframe module. I have a 320x carry. most comfortable midsize/full-size gun I’ve ever held and shot. It’s a totally different angle and feel from the round grip 320

All the standard 320 grip modules feel "plump" to me and remind me of the feel of a 226/228

The X-frames as more "flat" on the sides to provide more feedback as to the orientation of the gun in your hand

You might try to Wilson Combat grip modules as they are based on the "Small" module and have a bit more contouring. Supposed to remind users of a 1911

I and several others who have tried them prefer the Wilson Combat grip modules. They are thinner from side to side and that can help with trigger reach.

I have had a couple Sig "X" series grip modules in the small size and was quite happy with them. They are both thinner and shorter-(front to back), than the medium size and even more so compared to the standard roundish looking stock grip modules.

I don't have a small grip module to measure (could have sworn we did, but I can't find it), but the distance between the trigger bow and backstrap on a medium module is roughly 2 5/8" (had to measure with a tape because I don't have any calipers handy), and the same measurement is 2 7/8" on my large module, so there is a difference in trigger reach between the modules. Presumably the reach on the small would then be a bit shorter than the medium. There's also a reduction in the circumference with the small module, so that should improve your reach even further.

Hello All,

Thanks for all of the insight you've shared.

I finally found the Full Sized Sig-brand Small grip modules and received it today.

My reach issues are resolved!!!!


Now I just have to decide if I want to use a Gray Guns or Apex trigger setup.


My existing trigger 'breaks' at about 6.5lbs. My goal is around 4.5-5lbs, with less reset [if possible].

Now to research the posts on these two triggers for a few months before splurging.

Thanks again!

The best 320 trigger, IMHO. The flat trigger is amazing...

You can get less reset travel with the Apex Tactical Forward Set Sear (FSS) kit...they both address overtravel

GGI offers a replacement sear that Apex doesn't, Apex offers a modified trigger bar that GGI doesn't

I just got both and pick and chose which parts I wanted to install
