Sig P320

[Mick238]

I took the p320c to its first and my first ever shooting match. I managed to take second to last in production minor. That puts the gun up to about 225 rounds through it and so far zero issues.

As for my shooting clearly some more trigger time would have been good. I was over working it like mad and getting lots of low left pull. I'll chalk it up to nerves at my first event. Excuse making (; I used the holster that came with the gun and made a couple kydex mag holders which all worked fine. Reloads went smoothly but I never had to fire till slide lock so I am not sure if my thumb was hitting the release or not. Now I'm looking forward to getting some more range time and make it to a few more matches.

Edit I'm not sure how helpful the overall score is but I guess I managed to be 41 or 48th overall. Yay for being a little better than some people haha.

That apx take down lever looks pretty massive as well. I still think glock has a good setup leaving the frame space unobstructed.

For me, it isn't the physical size, but the prominence. The P320 TDL has a noticeable stepped ridge, and sits atop the frame. The APX appears to be basically flat, and slightly recessed; similar to the M&P and FNS, neither of which I even notice.

Those look great ... Nice job!

I agree the lack of a ridge probably makes it better but i find that if I get my hand up as high as I want the edges of the TDL seem to be the main culprit of the rubbing.

Thanks, they worked great for what I needed. They're a little rough around the edges as I'm still trying to get the hang of the kydex.

Haha I don't doubt it will show wear as I use it. Just some of the spots where it is showing wear seemed a little weird. Mostly in the last pic where the edges of that relief cut show wear.

The wear at the rear of that relief cut is from the top of the breech block as it slides under when it unlocks. Every Sig I own has that. I would imagine that any gun with that style of barrel lockup will show some wear there. I usually dab a little grease there when I lube the gun.

Not sure why there's wear farther up, unless it has something to do with how the slide was held when it was coated.

Yeah, it's the marks farther up that had me a little disappointed maybe. Hopefully it won't be an issue.

Hit up the range again today and put another 170 or so rounds through the 320. Getting better with it, still have to be careful to keep my thumb out of the way of the slide stop or the slide won't lock back on an empty mag. I feel like the trigger is just a little bit heavier than I expect it to be and I tend to be a little low left with most shots.

One thing I noticed is my trigger finger is getting covered in black soot. Is anyone else experiencing stuff coming down through the trigger hole?

Here is a pic of 15 rounds at 8 yards.

The P320SC (sub compact) guns are actually shipping with a redesigned trigger that fills the hole in the frame above the current trigger. It might be something to try when they becomes available unless you want to by an SC just for that. When I called two weeks ago to order grip frame modules they didn't have a part number for the new trigger yet.

[Mick238]

Are you getting the black trigger finger as well? looks like that SC trigger could stop it.

Mick,

I have not noticed that. Most who were looking to a feature like this complained about getting fingers pinched. I haven't experienced that either.

[Mick238]

Hmm interesting. I did notice if I got my finger at the very bottom of the trigger it kind of pinched but not too bad and I'm not sure how filling the gap at the top of the trigger would help. I'm a little worried if my gun is releasing vapors to a place it shouldn't be maybe something isn't locking up correctly.

I'd guess it has more to do with the ammo you are shooting, powder, bullet specifically, than anything wrong with the gun. I know I'll end up with black finger from my Glock, sometimes, depending on what ammo I use.

Ok, I've been shooting some factory PPU ammo, maybe it is just dirty. I've never experienced a black finger like this from either of the 2 Glocks I use but I haven't shot PPU ammo before. I'll Grab some different ammo and see if it changes anything.

I love my full size P320 9mm. But, I agree it is a tad oversprung. I would be happy to snip off a couple coils, if I had a spare. Does anyone have success with this?

Does anyone know when the GGI Guide Rods + 1911-springs are going to start flowing again? I don't want to order another stock spring when I won't be able to use it with the new guide rod, which I don't know when I will be able to get.

[alma]

I cut 3 coils and the gun still ran fine.

If GGI is out then you can order a similar replacement guide rod from Springer Precision

Thanks, I posted the same link and when it refreshed, I saw your post.

I very new to this forum and its been very helpful already. I am picking up my p320 next week. I think I have read all of the posts in this thread topic and I have a question about the 9mm spring issue. Will the 40 full size experience the same issue of the spring being a little to heavy? I thinking of trying IDPA with a Power Factor load in the 135 to 140 range...

Thank you,

Chris

Chris,

I don't know anyone else running 40 minor in the P320 but I would definitely recommend getting a noncaptured guide rod and a light recoil spring calibration kit.

That slide will be moving pretty slow compared to stock so you will want to tune your recoil spring to your load.

Picked mine up last night. I didn't want the Siglite sights but it was the only one I could find local.

[alma]

Nice stippling. Did you do that last night?

I sold my SIGLite sights to someone on the SIG Forum who had purchased contrast but wanted night sights.

No. I had ordered the small grip module a few weeks ago and did the work while waiting for the gun.

I'll give the sights a try and see how they work. I usually put Ameriglo "Hack" sights on my guns but I'll see how these ones work out before I order them.

Alma,

Thanks for the quick reply. Since I have had to weight to pick up the p320 I'm not as familiar with some of the details. Non-captured guide rod? How is it different from the original sig guide rod?

I'm also thinking I would like to get several hundred rounds thru it prior to starting to hand load for it and prior to changing anything about it.

nhjeffs,

I also didn't order it with the nights sights it has come with...

All,

This is really great that you-all share your experiences. My sailing community does the same and it really helps people get up to speed quickly...

The guide rod and recoil spring assembly are one piece. An alternative is a 1911 FAT guide rod, with appropriate spring for your preferred load.

[usa259]

Thanks ClayK. I guess I am not familiar enough to know the difference, yet. should probably wait until I pick it up and check it out compared to the pictures offered in this post...
