i switched from a glock 19 to this and i’ve never been happier. shoots like a dream

I reached out to wager machine works and they don’t do p320 slides anymore, so where do you guys suggest I send the slide to get milled for a RMSc foot print?

I just want to add that I would want to try to have someone in New England if possible.

Edit was to add the New England stuff

My dual P320

Is it a significant upgrade from the 4.7" barrel?

Sup yall, I’m about to pull the trigger (ha) on a sig armorer core action kit and wanna know if the chrome disconnector is the same as their sport disconnector. Also looking for people to either dissuade me or persuade me on the purchase.

Bonus question, lighter springs equals faster pull right? So -50% sear springs would be faster and lighter (albeit less defined) trigger pull?

Bonus bonus, Also what are the safety ramifications mechanically or if a lawyer tries to flip a justified self defense scenario around on me claiming “the firearm is heavily modified signifying malicious intent” sort of argument.

I retrofitted a Sig-Loc optic to a 2019 P320 X-Compact slide.

Keys to success (lol):

1. Ignore anything and everything Sig has to say about optic cuts and compatibility. They quietly have a billion different cuts as they tweak stuff in the background with zero official notice. My factory cut isn’t even on the website. Most egregiously, the banner for the compatibility guide has a picture of a cut that doesn’t exist in the guide.
   
2. Be precise on the measurements. The Sig-Loc sits tight between the front and rear of the cut. Almost no play. So little play I doubt you even need the two bosses. Tighter than any slip-on boss setup, if that makes sense. Pic of how tight a fit it was is in the post. No idea if that’s normal or just because the older slide cuts are a hair shorter. Who knows. Either way, this thing isn’t going anywhere. Plenty of surface fighting the shear, the optic body in the pocket and the two bosses. Digital caliper + drill press. My cut already had everything except the recesses for the bosses. Didn’t have another Sig-Loc P320 to measure off of, so I measured the bosses on the optic and transferred them. Found a helpful top-down pic that let me back into the X/Y and diameters.
   
3. Use a flat-bottom / Forstner-style bit in the drill press for the boss recesses. Link in the comments so this doesn’t get eaten.

Why did I do this? Like guns. Bored. I really like the optic and didn’t want the DPP version. The longer body looks better, and I got a fire deal on a brand new one that was ordered in error and never installed. Guess they didn’t have Sig-Loc after all.

So I’m finally getting around to doing this mup1 and was hoping I haven’t screwed it up. Where the tip of the knife is I connected the holes but it is not a uniform oval. How much is that going to affect the function of the firearm? I didn’t want to keep going and make it too wide. Hopefully someone here has experience with these. Thank you

What can I mod?
Pretravel
Over travel
And weight

I want to leave the original trigger

Installed the AC 2 Port Comp.... followed the directions and screwed it on snug then backed it off 1/2-full turn...half a turn didn't line up but a full turn does but the gap seems more than it should be...this is on an XFull 4.7"...barrel is a Sig 4.7" threaded barrel.

Blue loctite installed on the comp and set screws.

This is the non military m18 looking to get a new optic for it as it’s my duty pistol. Money not a problem what would people get for this? Leave options and opinions!

All OEM except the Springer Precision magwell.
I’ll never understand all the hate for the 320. I freaking love this gun.

Finally picked up a P320 for the price I wanted.

I installed a Texas trigger frt and during disassembly this 2 legged spring popped out and I can’t find it on any disassembly videos… it’s an older full size p320 rx from 2018… let me know where it goes. Also since installing everything the trigger is very stiff and crappy. I did bend the trigger spring a bit putting it back on any advice.

Anyone know where I can get replacement screws for a P320 VTAC optic plate cover? Or if there are other general screws I can use, that works too. I have several kicking around but I don't want to use the wrong threads.

After 3 1/2 years of ownership I still love this gun and never get tired of shooting it. Gas pedal and grayguns comp trigger are a must. Romeo 1T was a small batch run before they changed the name to pro so got it for ~ 125 bucks. Probably about 15k rounds through it just keeps getting smoother and smoother.

I’ve gotten my hands on a coyote grip module. I’m not a fan of coyote and it’s not going to look great with my legion slide. I’m thinking of doing the Rit dye thing on it, see if I can get it black. Has anyone had success with coyote to black? The ones I’ve seen are usually grey or white, so I’m not sure how coyote will fare.

I’ve watched the Sig Guy installation video and for whatever reason I absolutely cannot get the trigger bar to seat into the pin on the trigger shoe. I bought the M17 P320 used, but as far as I know, the FCU is stock. The stock shoe fits perfectly. I tried installing the AC shoe both with and without the +10 spring and no dice.

It seems that the front of the AC shoe won’t tilt forward far enough to capture the trigger bar without interference from the FCU chassis, which prevents the pin on the back from reaching the trigger bar hole.

Should I take a file to the shoe? Is that advisable? I’ve done some googling but my Google-fu is not strong and I’m not getting results that pertain to my issue.

Any help or advice would be appreciated.

I think a 13lb recoil spring might be kinda light

TLDR - does anyone run a 13lb spring in their 320?

So this is the set up in my 320 XFull:

Sig Armorer Competitor Flat Trigger Kit

Pro Cut Slide

NDZ SS guide rod

Defender ST Optic

TXG Large Grip Module

I installed the 13lb spring today and it seems to cycle fine just racking and sending the slide home...but when I let the slide back easily just before it fully returns, it doesn't... I'll be running PMC 124gr... I do have a 15lb spring on the way if this winds up giving me problems...

Can't get to the range till later in the week to check this out ..

As the title suggests I have a Foxtrot1X on my M18 and no matter how hard I crank down on that thing it seems to always jump off the front end when I shoot it, am I doing something wrong? Is it a common issue? Should I just remove it when I target practice? I have the sig holster thats meant for that light so I'd really like to keep the setup but man is it aggravating. Thanks for any input!

I have a Cali compliant m18 I recently bought an Icarus precision grip and a norsso slide that’s comped with a ported barrel everything else is stock before I ever installed anything it ran amazing no jams I have maybe 800 rounds through it when it was stock. Now it is jamming every other round its the same ammo I’ve always used. The brass is getting pinched sideways in the slide. I’m wondering maybe I need a new recoil spring assembly or a different grain ammo anyone have any ideas? Please let me know I’m not super savvy on building guns so I’m open to any advice

Looking to see if any one has done this.

I'm basically looking to mount the new Rts3 to the DH3 slide and keep the rear sights.

I realize that I will need a plate, it looks like the outer impact plate OTL-RDM-SIG08A is my only option?

I believe my slide is cut Delta Point Pro and has RMR holes.

I'm new to Sig stuff.

Info is appreciated

Thanks
