Shipped my 45 on 12/5 and she will be home tomorrow 12/13, thats what I call service.

Thanks Sig

My 2nd compact 320 was delivered to Sig on Wednesday December 6th and I'll be receiving back on Thursday the 14th.

My Compact came back today, and the Subcompact is scheduled for delivery tomorrow. I dry-fired it, and the trigger doesn't feel very much different to me.

Also, as far as I can tell, when cycling the slide to reset for dry fire, the reset point isn't noticeably different than it was before. I'd heard about having to retract the slide almost all the way to reset, but that doesn't seem to be the case with mine.

I have now had two P320s modified. After the first one came back, I compared it extensively to the non-modified one in dry fire.

I agree there is not all that much difference in trigger action after the modification. The main difference for me is that the modified trigger breaks a bit lighter than the original. That is true for both of my pistols.

Apart from this, in dry fire comparison I felt that the pre-travel for the modified trigger was a little smoother (although not shorter), and the reset for the modified trigger was a little more positive and audible. For both the original and modified triggers the quality of the break was just about identical, with some creep which I regard as the norm for a striker-fired pistol.

In live fire, the only real difference in trigger action that I can appreciate is a bit lighter break. However, the first time I shot my modified full-size P320 .45 ACP in live fire I did experience some trigger finger sting, which has also been noted by a few others.

Where your trigger resets will depend on what type of lightening cuts your slide had. On those slides with a long rout on the bottom right side of the slide, the pocket that is milled for the disconnector head when the pistol is modified will merge into that long rout, and the disconnector head will not get pushed down until it reaches the forward end of the rout.

On pistols without that long, right-sided rout the disconnector head gets pushed down as soon as it leaves the little milled pocket.

Did the recall and I'm not happy ! The changed the trigger to a fly one witch I like ! But the trigger is stinks it a harder trigger pull and the brake isn't clean ! That was the main reason why I bought it was the trigger . I chose the 320 over the Glock guess can you say trade in !!

Sending my P-320 in today.
It is an early compact with the relief cuts in the slide.
Took a few before measurements and will post after measurements when the pistol is returned.

Before:
Trigger pull (avg 5 pulls w/Lyman digital gauge) = 6 lb + 5.5 oz w/crisp break
Rearward slide travel required for disconnector to reset = 10 mm
Trigger reset distance = 3.23 mm

At last some numbers about trigger force! Many have expressed impressions about the "new" trigger (after slide cut and addition of disconnector), but Steve seems to be the first to tell about initial force and provides hope to tell about the "after."

With Gray trigger one can see something like 4.5 pounds-force. Has anyone sent-in a P320 that includes a Gray trigger?

P320F 45 Using Lyman gauge. Not sure that the trigger curvature is the same which could cause the slight difference in pulls.

Before Upgrade: 7/3/2017 Std Trigger Average of 10 = 7lb 9.0oz

After Upgrade: 12/12/17 Std Trigger Average of 10 = 7lb 6.2oz


No discernable difference in reset or travel comparing P320C 45 not yet sent to Sig vs P320F

Yes, that’s nice:

The pull weight [after the modification] was 5 pounds, 7 ounces. The gun has about 1600 rounds through it and out of the box originally the pull weight was 6 pounds, 0 ounces. With the Apex trigger before I sent the gun back for the “upgrade” the pull weight was 5 pounds 1 ounce. The pull weight increase over the Apex trigger is probably due to the difference in the leverage contact points between the two triggers.

I probably missed it but a thought regarding the disconnector addition and the slides with lightening cut in the new milled pocket path. I have no issue with the increased slide travel to reset the trigger. But with increased slide travel the disconnector doesn’t really do its job. Without the lightening cut the disconnector activates with the slide roughly 3/16” out of battery leaving a dead trigger and preventing a possible out of battery firing situation. With the lightening cut the disconnector doesn’t make any difference in the function of the pistol compared to a non”upgraded” pistol. The trigger stays active with the slide well out of battery.

The fact that the pistol was initially designed without a disconnector strikes me as odd but since Sig has decided to add one shouldn’t it function properly? Am I looking at this wrong or something?

Having an early version with the relief cuts, that was my concern as well and I briefly commented on it on page 14 of this thread.
Testing my pistol prior to sending it in, I placed a shim made from a business card between the barrel and slide thus holding it slightly out of battery.
The trigger could in fact be pulled but the striker block was not activated so the striker forward movement was impeded and it appeared the barrel would be way out of alignment from the striker, hence the striker would not be able to hit the primer.
In other words, based on the original design it appears the pistol remains in battery until both the striker block and barrel alignment will prevent it from actually firing.
Someone like Bruce Gray or others who have significant experience with these pistols could probably describe this better.

Nevertheless I will retest this upon my pistols return and if it appears to be an issue it will be going back to SIG.

That makes sense. So the original design relied on the striker block as the out of battery firing safety in addition to, theoretically, not allowing the full travel of the striker unless the trigger is actually pulled.

FedEx label just hit my inbox. Should be able to get it sent off tomorrow.
Hoping it's back in time for my mid-January hunting trip.

ETA: RANGE UPDATE 12/15
Made it to range to try out new trigger job.
Despite nearly freezing temp, ran almost 100 thru 320 9mm, first to check function/feel of the trigger, second to enjoy the pleasure in a good trigger having been subtly improved.

here's my observations:
Looks: yes, that is a different trigger, sleeker & without the boxlike reinforcement on the rear of the curve; Has a flatter contour similar to the Kidde trigger on my 10/22. No longer a clone to the 229 curve.

Pull: while didn't get release metric recorded, this new trigger pull seems to be somewhat lighter AND smoother. I like the flatter contour.

Reset: definitely improved, more rapid reset time; slide rearward movement is something between 3/8~1/2";

With this short of a test run, I regard the new trigger as a definite upgrade.



Sent in 12/5; back in my hands TODAY 12/14!!!

Impressive turn around;
impressive trigger contour even feels lighter to my dry fire, haven't measured; reset seems tighter @ a tic under 1/2" slide movement;
will be at range as soon as above freezing.

oh....looking for a creative use of the "25% off your next order" card.....

Received my email and printed my label last night. Im going to try and get mine in the mail tomorrow, just in time to get lost in the Christmas rush....

Ok... I go to the Sig store to try to use my 25% off coupon and there is no place to enter it? wtf??

SIG used to issue 20% off coupons when you registered a new pistol for warranty. They stopped that a year or so ago. Those coupons could only be used for phone-in orders and were not good for every item in the store, I found.

Perhaps these coupons can only be used for phone-in orders as well.

There's a big "Discount Code" box at the bottom of the shopping cart page, but you have to be on the page and not just in the little popup window. In that window click "My Cart" and that takes you to the full page.

All boxed up & waiting for a lull in the office to run over to the FedEx hub to drop off.

Edit: Dropped off at 1030. We'll see what the turnaround time is with Christmas & New Years quickly approaching. I'm off for a few days before & after Christmas, would be perfect if it came back then...
