Hello all. New bodyguard owner. Read many of threads about the stiff new mags. Keeping them loaded has helped. I have noticed something weird. After leaving the mags loaded for a couple days I unloaded them to see if it was easier to load again. It was. although still need a loader assist on the 12 rounder. What I noticed is almost all the rounds have a crease in the casing. The rounds were never cycled or even the mag never inserted in the gun. It is not a crimp as I inserted new ammo from a box and verified none has this crease. I think they are having the be compressed down so hard they are being pushed into the sidewall of the magazine and being creased by the area of the mag that the arrow is pointing to. The mark lines up perfectly with where the crease is. Any thoughts on this? I am 99% sure the rounds will still fire, but it bothers me rounds are being damaged on a gun I will possibly carry.

edlloyd,

That’s a new issue for the BG2.

I believe your observations are correct.

I suspect it’s another quality control issue for S&W.

I am amazed that the firearm manufacturers have so much trouble producing the simplest 6 piece component on a magazine-fed pistol.

I've only encountered that on the top rounds of a magazine usually inserted. At least that's where I thought the issue was. Never encountered it with rounds in a magazine, just top one.

I leave mags loaded all the time, I'll take a look tonight.

That is my experience as well, if I load the very last cartridge into the magazine without using a loading tool. The rim of the cartridge being loaded into the magazine puts a crease in the top cartridge in the magazine just like the OP's picture. I have not had any malfunctions related to it.

Because that's where almost all mfgrs try to shave down costs. Why do you think Mec-Gar is the golden standard & is making $$ hand over fist?
 
No issues with the two magazines I keep loaded all the time for my BG2.0, that's usually the two with my defensive ammo.

I have six others which I've had loaded at various times with no issues. So not thinking this is a systemic issue.
 
Just for gits & shiggles I looked very closely at 9 rounds fresh from a new box inserted into my 10-round mag with an UPlula.

I removed them with my fingers and looked closely. I could see the crease made by the mag. It is just deep enough to feeling it with my finger nail. The crease is only on one side and about 3/8" in length.

So all 9 rounds had this crease?

That is a good question.

Here’s an answer:

I loaded 10 rounds from a fresh box of PMC Bronze FMJ into my 12-round mag. With the UpLULA I can only get 10 rounds loaded with adequate force. I can get the 11th round loaded but I have to put more pressure on the UpLULA than I feel comfortable with. I have never been able to get 12 rounds in the 12-round mag or 10 rounds in the 10-round mag.

I removed each one by hand and inspected the round visually and with tactile feel with my finger nail. Starting with the last 2 rounds #10 and #9 – there were no visual marks, which is logical because those 2 rounds did not get compressed into the mag far enough to hit the deepest area of the stampings, which is 4 rounds from the top on the mag.

With #1 being the first round inserted – no visual marks.

#2, #3, #4, #5 - very light mark, no felt crease.

#6, #7, #8 – visible mark and felt crease.

#9, #10 – no visible mark and no felt crease.

The deepest area of the stampings is located at the 4th round from the top. So, rounds #6 thru #8 are receiving the most force from the UpLULA as the final #9 and #10 rounds are being loaded.

The nickel plated Hornady Critical Defense 90 gr FTX showed similar marks and creases.

It’s interesting to see the difference in design between a 12-round Sig Sauer P365 mag and the S&W BG2 12-round mag. The Sig mag has a stamped channel about 0.114” wide running down to the end of where the rounds are loaded.

The S&W BG2 has a stamped sharp crease about 0.034” wide and about 1.0” in length. The peak depth of that crease is right at where the rounds begin to stagger.

I have no idea if the creases on rounds #6, #7, and #8 have any effect on feeding or other functions.

As I have posted… My BG2 has been gunsmithed. The chamber feed ramp has been polished. I have zero issues with Hornady Custom 90 gr XTP, Hornady Critical Defense 90 gr FTX, Federal HST 99 gr JHP, Winchester 95 gr FMJ Flat Nose, Winchester PDX1 Defender 85 gr BJPH, Sig Sauer Flat Nose, Magtech 95 gr FMJ, and PMC Bronze 90 gr FMJ.

Both mags have been opened, cleaned, and lightly lubed with Clenzoil on the spring and inside of the mag tube.

I’ve noticed that with mine as well.
I own 2 BG2s one I carry in Fl one in Nj
The Fl gun had an issue with the follower jamming up on reloading.
After purchasing my second I noticed no more issues.
I contacted SW and after they tried to give me the run around twice they finally sent me new springs and followers.
Problem solved!
Put a pile of rounds thru my Fl gun with no issues
 
I also have two of these pocket pistols; one in NJ and one in FL, and I also had creased cases after loading. I bought a printed loader from Amazon to deal with the difficult loading of the last two rounds in the 12 rd mags. Not sure if that resolved the issue, but I was blaming the force of loading for the creases. Now I have to reconsider if that is the case.
 
I have eight of the BG2.0, 12 round magazines, use the Uplula magazine loader and push all 12 rounds into them, though it take a lot of force to get the last couple of rounds in there. I've never noticed a crease on any of the rounds like this. Are you pushing the Maglula plunger all the way back when loading rounds?
 
Anybody who is concerned and wants to know if the magazines are causing the creases can blacken both sides of their cases with a Sharpie and load them in the magazines with the markings on the side. I'm not worried about it.
 
Looks like a pressure mark at the base of the bullet commonly formed during the manufacturing process. Some of my reloads have thus look. And who cares as long as the pistol is reliable. The next complaint will be that the poor little gun doesn't make your coffee hot enough or clean itself.

I notice that too but haven't had any issues whatsoever with chambering or cycling while firing so I carry with confidence. Another note is after firing the brass gets reformed and successfully reloads.

This was my thought. I have rounds that come directly out of the box with this mark.
