thormx538 Posted August 13, 2019 Share Posted August 13, 2019 (edited) The TXG grip module has me thinking about a 320 Open gun project again, for fun. Plenty of options for comps and barrels, but does anyone know of a fixed mounting system for the optic? I'd imagine you could drill/tap the FCU for rigidity (there's a lot of real estate on the left side, and a little bit on the right), but the question is whether or not something exists already for this or if I'd have to prototype/modify an existing one (such as modifying a Carver XDM mount, or an SJC/ALG Glock mount) I've seen a "Neumount" rail mounted one made in the past but they seem to be out of business now Edited August 13, 2019 by thormx538 Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 13, 2019 Share Posted August 13, 2019 Hello: Why not just mount the red dot on the slide and call it good? Thanks, Eric Link to comment Share on other sites More sharing options...
thormx538 Posted August 13, 2019 Author Share Posted August 13, 2019 Figured there had to be some downside to that with 9mm Major, either in terms of tuning (reciprocating mass, ejection, etc) or lifespan of the optic. Slide mount would also preclude a C-More from being used Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 13, 2019 Share Posted August 13, 2019 Hello: If you want to use a standard C-More slide ride then I would look at a two sided mount that is screwed to the frame with a metal support plate on the inside of the grip to sandwich the frame. That would give you a nice secure base. Thanks, Eric Link to comment Share on other sites More sharing options...
Rudukai13 Posted August 23, 2019 Share Posted August 23, 2019 (edited) I’ve been looking for something like this for quite a while. Unfortunately to my knowledge there aren’t currently any of these kinds of mounts available on the market, however I’m aware of several companies that are either known or rumored to be working on metal grip modules (aluminum or steel). Once one of those gets on the market, it will lend itself much better to a frame-mounted optic as you’ll be able to drill and tap the grip module itself. You could also join me in encouraging/pestering SJC Guns to develop a version of their micro dot mount for the P320 platform, which would install by mounting to the FCU through the polymer grip in the same way their mounts for Glocks and M&Ps currently work; https://stores.sjcguns.com/sight-mounts/ Edited August 23, 2019 by Rudukai13 Link to comment Share on other sites More sharing options...
thormx538 Posted August 26, 2019 Author Share Posted August 26, 2019 A buddy of mine is going to mock something up in Solidworks for me when he gets a chance. The issue I see is that the serial number area is a prime mounting location in terms of where to drill/tap. This wouldn't matter on an 80% FCU obviously.

I just received a Neumount in cerekote for my CZP09 to mount a Holosun 507C (Poly fun open gun project too!). Took a few weeks. Excellent fit. Good guy I suspect is a one man show, took the time to call me back and answer questions. The website is not mobile device friendly but fine with a PC/Mac.

SDTMatch40 Posted September 11, 2019 Share Posted September 11, 2019 Just a thought, the C More Slideride was originally designed to ride "on the slide" of a Glock, so it should withstand the abuse if you mounted directly to your slide. Good luck with your project, SDTMatch40 Link to comment Share on other sites More sharing options...
SDTMatch40 Posted September 11, 2019 Share Posted September 11, 2019 I believe the Glock Store offered a universal mount that attracted to the accessory rail or any pistol to mount a stationary red dot. I haven't looked lately but might be worth investigating. Regards, SDTMatch40 Link to comment Share on other sites More sharing options...
Rudukai13 Posted September 12, 2019 Share Posted September 12, 2019 If you’re willing to wait a bit longer, there are several companies working on aluminum/steel grip modules for the P320. One of those would make for a much more solid mounting point, as you could drill and tap the optic mount straight into the dustcover portion of the grip module as on a 2011. Here’s a teaser from one such company; Link to comment Share on other sites More sharing options...
thormx538 Posted September 12, 2019 Author Share Posted September 12, 2019 Interesting. I'll have to follow them on IG. I haven't done anything additional on this since making the thread. Probably a winter project. Link to comment Share on other sites More sharing options...

I believe a in order to be legal in CO it has to start out as legal in Production. Different frame would automatically DQ in CO. Would only qualify for Open with an optic or possibly Limited (10) without optic. But OP was inquiring about Open so then it would be legal.

jcc7x7 Posted September 12, 2019 Share Posted September 12, 2019 Rules say you can change the grip??????!!!!!!!! and we know just about everything is legal now a days (maybe we should change the name of production to Production open ) It's meant as a joke, take it that way!

Rudukai13 Posted October 4, 2019 Share Posted October 4, 2019 The Atlas Gunworks 2011 optic mount fits the P320 like it was made for it. If you can figure out a way to reinforce the polymer dustcover, you can use the Atlas mount for your open gun project; Link to comment Share on other sites More sharing options...
Aircooled6racer Posted October 5, 2019 Share Posted October 5, 2019 Hello: Look at what I said above about adding a metal plate on the inside of the frame to sandwich the plastic frame in between. A little milling to clear the plate from the slide and you should be good. Thanks, Eric Link to comment Share on other sites More sharing options...
Degnan Posted February 1, 2022 Share Posted February 1, 2022 Is this project feasible now that Sig released the AXG grip module? Link to comment Share on other sites More sharing options...
X5SigChris Posted February 1, 2022 Share Posted February 1, 2022 I haven’t figured out the picture adding feature yet but if you have IG, search dfeltyberger. He has a open p320 he’s working on. May be able to steal some ideas. also, that aluminum grip looks like a game changer for anyone, like me, wanting to tinker and build an open gun also. Pretty awesome.

Yes I used the Icarus Precision grip module, but the AXG will work just as well. The Atlas Gunworks optic mount fits without modification, you just have to drill and tap the holes. I know of two other shooters who have built Open P320s using the Atlas mount and aluminum grip modules and they’ve had no issues either Link to comment Share on other sites More sharing options...
