This comes up so frequently, we might do with a sticky, but I'll repeat the friendly advice often given here:
If you don't have an UpLula magazine loader, it will help to get one, at least at first.
If you have the mags apart, inspect the followers for casting marks, scrape or buff them off, and give the mag tube a light wipe, perhaps with the dry lube of your choice. Reassemble with the spring in the correct orientation.
Load, then unload them to full capacity, a few times. You may need to let them sit at 16 for a while, then you will find you can get 17 in. Yes, you will have to load the 17th with some enthusiasm.
Barney loading a mag may be useful, if you want to get to N+1 for a carry weapon, perhaps.
For normal range use, follow the procedure listed in the P365 manual, and load from a fully loaded magazine from a locked slide, only.

X Macro Magazine
I just got a X macro a few weeks ago and noticed that the mags are not only stiff when loading the 17th round but I really have to jam it in the gun for it mag to lock in has anyone experienced this? ….on a side note I took it to the range (put 70 rd through it) and it jammed up on my FIRST...

Racking a 365 With a Full Magazine
Can u do this with yours if you put the mag in while the slide is forward? I have about 500 rds since pulling it out of the box. It seems I can't rack it on a full mag of 10 rounds Well lubed, too. No other issues. I would much prefer to load 10 rounds and not have the +1 in the chamber...

365X magazine
Just received my new 365X after evaluating competitors. I'm having a very hard time loading the magazines. I'm kind of familiar with this type of magazine and the procedure required to put the rounds in, but it seems like the spring is way too strong. I'm a 170 lb male with fairly strong hands I...

Stiff magazines
Knowing that the mags are somewhat hard to load into the gun. Is it ok to leave the fully loaded mags in the gun? Wondering if it would somehow effect the slide if a fully loaded magazine is pushing against it pretty hard.

Thank you for posting all of those mag issue posting/threads. I have breathed a sigh of relief about my XMacro TacOp. I just trade my non comp XMacro for this very same reason. Obviously it was a knee jerk reaction. Especially being brand new to Sig firearms. As a side note I was seriously contemplating selling or trading the other XMacro.This comes up so frequently, we might do with a sticky, but I'll repeat the friendly advice frequently given here:

The magazine spring itself can be the issue. SIG springs nest, one coil within the next, as they are compressed, which is how they achieve the amazing mag capacity. Ordinary mag springs simply stack as they are compressed.
But, sometimes, a few coils stack, rather than nest, and it is virtually impossible to fill the magazine. Unless the coils "adjust", relative to each other, the problem never goes away.
I've had a couple 12 round mags that displayed this behavior; replacing the mag spring with NDZ+5% aftermarket resolved the issue.

Great sticky.
I have found that the double stack mags in the new generation of micro pistols (not just Sig) can initially be tough to load to capacity. The Maglula UpLULA is a great asset to have for loading any magazines. With time and use I haven’t had any that didn’t relax and get much easier to load.
As to cleaning magazines, I believe it is essential. I disassemble and clean every new magazine and regularly clean them throughout their use. It’s amazing how many new magazines are wet with oils and loaded with manufacturing grit. I have also found that many of the polymer followers have a lot of flash and sprue from the injection molding process that needs to be trimmed off. I have also had magazines with excessive burrs on the feed that needed to be cleaned up.
After I disassemble and clean my magazines I wipe them down (and the components) with a silicone cloth.
This cleaning routine has worked for me for a long time without any excess oil to attract and hold debris.
Just my experience and opinion.

Thanks again for your excellent suggestion, which I will try.
This, below, is the 10 rd. mag I'm workin' with. I've got three more for my new P365, and they're all tight as Dick's hatband!🎩

Great post! I wish I knew this a week ago.
Truth be told, I was so %*$# disgusted with the mags that I threw the loader in the trash. I ordered another one.
Today, I'll open-up these 4 mags and apply Hoppes Dry Lube to the springs. Then, I'll cram 10 rds into the magazines and let them sit over the weekend.
Thanks again!

I've found that the follower likes to hang up on the hole that holds the mag in the pistol because the hole they punched in the mag has a bur. disassemble the mag and carefully smooth the edges of the holes. On my p365 it would hang up on round 5 before i did this.
For 17 round X Macro magazine users, I installed the Radian Weapons TRU-17 base plate which is designed to provided a hair more vertical room, making loading by hand easier. It works.
My P365 380 owners manual recommended a light coat of CLP on the outside of the mags and the mag springs with a light wipe down after a few minutes but none on the inside of the mags which just get a dry, clean microfiber cloth pulled thru. I did this on my initial clean/lube before I shot the pistol. The result so far is 800+ rounds down range without a failure of any kind. It works so well that I now do it on my 2 9mm EDC micros which have never malfunctioned before or since. YMMV
I picked up a 21-rd P365 mag the other day, and have twice run it from full capacity with 115gr ball ammo, in my standard (10rd grip) pistol. Both times I had repeated failures to chamber or even strip a round...
Does this sound like a brand-new mag needing to wear in, or a problem interfacing with the tiny grip of the pistol? I don't recall issues with 15- or 17-rd mags.

I’ve never read a User’s Manual that a magazine has a “break in period”.
The mags should either work or not. If they don’t work, they’re defective.
Sadly, several magazines I’ve purchased were defective and I had to do “gunsmithing” to the followers or the feed lips.
There’s no excuse for firearm manufacturer to advertise and sell a very simple 5-piece component that doesn’t work.
I disassemble (except my Colt 1911), clean and lube my mags.
I purchased 2 P365 17-round mags and I could get 17 rounds in them. I returned to Sig.
The 21-round mag should work fine in a P365 Micro grip module without a baseplate for the mag well.
That’s just my worthless opinion.

"Lancer L5 AWM may have the issue nailed: lack of support for that longer magazine may be affecting the presentation of the top round to the slide for loading."
If that was the issue then ALL of extended magazines being supplied by several aftermarket and the manufacturers would be failing.

Lancer L5 AWM,
Protracted debates and discourse in a public forum is not my thing, however just to further clarify my comments and observations….
Obviously every mag, and every mag well and grip it goes into, can be different.
My “assumptions” are based upon actual measurements. Have you done any measurements?
I’ve been a gun owner since 1978 with magazine fed handguns. The only loaded mag that has nearly zero movement once inserted is my Colt Mark IV Series 70.
My 15-round Sig 9mm loaded, actually fits tighter with less movement in the grip of my P365 Micro than the 12-round Sig mag WITH the proper mating base plate… by about 0.044”
There are extended magazines on the market that do not have a base plate to mate the mag well. A failure due to “tolerance stacking” doesn’t mean anything unless you know what specific tolerances are designed-in to what components. Then analyzing the exact measurement data, typically “go/no-go”, to show which specific component and what out of tolerance measurement(s) cause a failure due to any combination of measurements.
I’ve shot my P365 Micro with the P365XL 15 round extended mag, no mating baseplate multiple times with zero issues.
If “tolerance stacking” is an issue causing feeding or another malfunction in extended magazines WITH or WITHOUT a mating baseplate, I believe it would be well-known.
By the way… your assumption regarding the length of the mag is wrong. The length of the mag, supported with a baseplate or not, once inserted, has no effect on any movement within the mag well grip. Pop a loaded mag into an AR-15 and see if you can detect any movement lengthwise, or it in or out. There will be lateral movement and that movement or tolerance is NOT an issue to cause a failure.
That’s just my worthless opinion.
