Question MA Compliant Grip Modules??? When???

I purchased a MA compliant P320 9mm Compact a few weeks ago. Beautiful gun like nearly everything Sig manufactures. I used a full size P320 at training classes at Sig Academy prior to my purchase, and that was the reason I bought the P320 Compact thinking (and herein lies my problem) that with the wonderful caliber and size conversion kits Sig sells for the P320, I thought going to a full size 9mm (or 40 or .357 or 45) would be no problem. So I purchased a 9mm full size conversion kit at the Sig Pro Shop in Epping, NH. When I got home, I realized that the grip module on the MA compliant compact 320 is unique in that it has two special grooves cut in the module near the rear of the grip to accommodate the MA required ambidextrous safety switch on the firing mechanism! The grip module on the full size conversion kit I bought DOES NOT have the slots cut in the module so the firing mechanism (serialized part of the gun) will not fit in the module...also known as making it useless until Sig manufactures a MA compliant grip module for the full size 320! UGH!!! Massachusettes does it again!

Does anybody know when/if Sig will be selling grip modules (with the safety switch cut outs) for those of us hog tied here in MA? I can obviously still use and enjoy the compact 320, but I bought a 320 because of the flexibility provided by the caliber/size conversion kits that Sig makes for the gun.

Thanks for any information that can be provided.

Please alway shoot safely!

Also a resident of the republic of Massachusetts and also a P320c owner.

I too would love to convert to at least a full size slide but I am OK with the compact frame. I however do not think that they make Fullsize magazines that are within the MA neutering laws.

I have heard murmurings that they are working on thumb-safety compatible grip modules but no one can even guess when they would be shipping. If you really wanted to, you could work with a local machine shop to measure out and get slots milled into a frame if absolutely necessary.

I have a P320 with the Manual Safety. Great pistol.

I will tell you it took many months for the Manual Safety to hit the market and I would expect for it to take just as long or longer for accessories for the Manual Safety model to catch up.

There have been some that have made the two special cuts with a dremel tool. That might be your best chance if your wanting it now. Just a thought.

You're seeing them locally because of the MA compliant issue. I've seen the handgun but but the stripped module to see what would be required to cut a grip module. I wouldn't hold your breath waiting for MA modules. Could be a while.

Thanks for all the feedback. I actually did try the Dremel approach. I traced the cuts on my compact module and then etched the outline on the full size module after measuring very carefully. I spent about 30 minutes CAREFULLY cutting the module. After some minor adjustments I was able to get the fire mechanism to slot in and get the take down lever to engage. The problem was I couldn't get a consistent striker pin action in dry fire. I would pull the trigger first time, rerack and nothing...second time, nothing...third time the striker would go. The only time I could get things to work with any consistency was by racking the slide by hand with the trigger pulled and then allow it to reset and dry fire again. That would work about 98% of the time. Otherwise it was anybody's guess when the striker would fly!
My sense is the tolerances between the mechanism and the module are pretty close and if something isn't lined up just perfectly, it's a misfire. I tried the full size barrel and slide on the compact module and no problems what so ever, so I'm thinking it is an imperfection in the cuts made to the full size module.
I guess I'll just keep waiting and use the compact instead and hope that Sig will produce MA compliant grip modules sooner rather than later.
Thanks again for the feedback. Still a big fan of Sig regardless!
Shoot safely!

Right now production takes precedence. Sooner or later that will be available for sale.

Can you show a pic of the MA compliant p320. Curious about the ambi safety.

This is NOT my P320 but one posted by another forum member. Mine is all black but this will show you where the safety is located on the slide.

Still waiting for word from SIG as to when the full-size grip modules (that will accept the MA safety design) are going to be manufactured. I tried using a Dremel to cut the notches in a FS grip conversion kit, it worked...sort of. The tolerances are VERY tight and as result I ended up getting occasional failure to fire problems which did not occur with the stock P320 compact grip module from the factory.

SIG (as of 3 weeks ago) had NO idea when they will be building the MA compliant grip modules. I'm going to the Sig Academy tomorrow for a class and will stop by the Pro Shop and see if they know anything. The other option would be to have a skilled gunsmith make the cuts in the module. It requires very precise machining of the plastic grip so the fire mechanism (serialized gun/trigger assembly) fits into the module perfectly.

For now, it's the P320 compact until SIG gets these new modules built.

Shoot safely!!

Likely any decent machinist with a mill could do the cuts for you. Possibly even a home-machinist with a drill press.

Could you provide a picture of your grip without the FCU (to show the alterations as made by SIG)?

If I want to screw something up really fast, I use a Dremel.

Here you go. This is my P320 (with X-Ray sights) and modified trigger. You get the full pistol, just the module with the FCU removed and a close up of the pesky notches for the safety.

Enjoy!

I wonder if the 320s they submitted to the MHS trials had the thumb safety.

Nice pictures.

Looks like maybe using the original as a template to locate the area on the new grip:

1. Drill a hole with the correct diameter for the bottom of the cutout.

2. Cut the flat sides with a fine-toothed saw.

3. File the flats to allow the fcu to seat.

Might be an opportunity for some small business while waiting on SIG to make these.
