I have, in the past, posted on the effect the taper of the Parabellum/Luger round, noting that it might affect how the magazine stacks the rounds.

Now I see something very unexpected. When I look at a 16 round magazine, loaded to my standard of 15 rounds, (Saves my thumbs) I notice that the nose of the round I see through the magazine lock opening is tilted DOWN, and significantly so.

Then I look at the indicator opening 15, it seems to show a perfectly level round. One would expect the follower to make the nose of that round tilt up.

I only have two 16 round magazines but both present the same way.

Is this unique to me or is it a common situation?

If the magazines operate reliably in the gun it doesn't matter.

You should also be aware that when some high capacity magazines are fully loaded they rattle, while others don't.

It's muchadoaboutnuthin...

Once again, if they operate reliably it isn't a problem.

Magazines (regardless of the cost) are expendable and are 90% of the time the one thing that causes stoppages within the breed.

O.K. Mr. Shakespeare, I got the message.

I have never had an issue of any kind with my SD9VE, although I don't have as many rounds through the gun as most folks here. I have some 10 round magazines and some 16 round magazines and they all work just fine.

It's just counter-intuitive, especially when one looks back at a thread that discusses the effect of the taper in the 9mm rounds. I posited just the opposite stacking issue from the one I just now observed. I suppose I never noticed it before is because I had no problem to solve, and still don't.

Thanks for the input.

Shakespeare? No

Longfellow...maybe

Can't load your mags fully?
Sheesh, what a wimp!
Just kidding, new springs are tight so one of the first things any semi owner needs to purchase is a Maglula UpLULA Universal Pistol Magazine Loader. Best accessory ever!
Saves so much time and wear and tear on your thumb as well as time loading.

I plan to stay with 15 rounds in the 16 round magazines. So far, loading 15 rounds hasn't been a problem. I do plan on getting a low-end loader, Maglula is clearly an over-priced item, especially for my needs, but thanks for the suggestion.

I have been thinking about a post response by moondawg about the reliability of magazines, especially the reports of Failure to Feed. Clearly my 16 round magazines keep the rounds more organized than those in a Winchester 100 round white box, but they are clearly not well aligned as you look down the various openings. My notion is that most Failure to Feed events are indeed magazine related. Just a notion, not an argument.

I have 3 mags , the 2 that came with it & a sigma mag I picked up for way too much during all the panic buying.
They all work fine & yes I can load 16. The sigma clicks in a little harder. Mags are plentiful now but still not cheep. So I figure I will stay with 3, I can load 45 or 49.
Anyway I have had the gun w/ 2 for 3 years & the sigma mag over 2 years so I have started keeping 2 loaded with 15 & rotate one that I leave empty between range trips. I hope this will extend the life of them.

You thing these mags are odd to look at, try keeping the stager right in a 25 round 22lr mag

My Remington 121 Fieldmaster didn't have that problem . . . Tubular magazine!

I like my 15-22 makes for real fun plinking , almost as much fun as finding ammo for it :roll eyes:

Haven't shopped for .22 ammo in some time. In my early days you could buy it everywhere, even in some drugstores - but those days are long gone. I do regret selling my .22 rifles when I retired back to Oklahoma 7 years ago. I sold them while walking around in a gun show for about 1/10th the current market! The only reference I had in mind is what they cost over 70 years ago. I recently came across a Fieldmaster parts list from those days. Things like Barrel for $12.00, stock for $8.00, etc.

On a related subject I was reading an analysis of the STEN gun, which was, in most versions, a 9mm weapon. One of the problems was designing a double stack magazine what could reliably channel the rounds to a single stack feed. The taper was hard to design and easy to deform.

That caused me to look at some Sd9VE magazines. Looks like S&W did a good job in that area and included a groove that stiffens that area, and may also be part of the > solution.

no need to rotate mags springs do not weaken even in loaded mags its the compressing and un-compressing of springs that wear them out so in shot all mags loaded all the time !!!
