if you have to short a mag for it to run right something is wrong somewhere.. either with the gun or the mag

 

Depends on the magazine and gun. For example, my USPSA Open Gun big stick I would never want to reload to with it full, top round is too tight. However, I have no problem barneying a round then seating the full big stick off the clock to start a stage.

 

Every magazine I have gets loaded to capacity, round racked and chambered, then mag gets another one added.

I moved here from California...I want my damn "high capacity" mags full

And as a side note all of our Glocks and AR's have never had a problem being loaded, seated or fired +1.

 

Same here...

And I have no empty magazines lying around; every one of them are loaded to capacity.

 

Very common with 30rd AR mags. With some AR's and mags, seating a full 30rd mag on a closet bolt can be very difficult. Same mag with 28rds snaps right in.

Edit: woops, didn't notice this was posted in handguns. Well, same logic applies to AR pistols!

 

It's good. Same physics.

None of my guns have any issues per se...but some ammo in the JHP variety feed better with one shy. Most of the time that leads me to try different ammo, but a couple of the semi's are just real picky.

 

And while I'm here...does anyone use (handgun belt type) horizontal mag carriers?

Yes, I have a 1911 horizontal mag carrier that Curt made and it's great. I can bend over and the mag doesn't poke my belly.

 

Full mag plus one in the gun, so no.

I make and carry horizontal mag carriers. Never thought I would like them. I'll never carry a 12+ rd mag in anything else now. I still carry my 380 mag vertical when it's on the belt.

Did you get those horizontal mag carriers with buttons to work like you wanted? I might get one or more.

 

I only do that with brand new mags or guns. Once they been used a little there is no need. Unless something is not functioning correctly.

 

I've seen issues with other people's ARs like @drypowder was saying. One guy shooting at gunfighter league was having problems getting his mags to seat when the bolt was closed and he was trying to do a magswap before he ran his weapon dry.

 

I load. One short on ar mags 30 and 40 rounders .some guys count l load to the top and back off one.

 

Obviously with each round inserted the resistance increases, but it seems with that last round the increase is significantly more than the others in most type of magazines. This often leads to the top round residing at a slightly different angle, especially with pistol mags. I don't shoot much formal competition, but for EDC I will typically load it full, insert mag with an open slide, chamber the top round and leave it that way rather than topping off the mag even though I'm capacity challenged with a single stack. It just makes it so much easier to work with the weapon and I have a place to put that extra round when I need to unload it. I always carry a spare mag and it's loaded one shy too, so if I ever do really need it there won't be any seating or feeding issues whether the slide is back or not.

When I occasionally find a mag that's tight on the last round usually filing a bit off the bottom of the follower fixes it. So no.

 

For carry purposes, or proper functioning of the mag, there shouldn't be an issue if the mag is fully loaded. (Some guns don't like to chamber the first round of a fully-loaded mag, but that's a gun design by gun design issue.) Shoot your carry guns from time to time to assure proper function, and otherwise don't worry about it.

The ONLY issue with a loaded mag I can think of is spring life. Depending on the mag design, a fully-loaded mag KEPT FULLY LOADED (as for long-term storage) can cause some mag springs to degrade more quickly than if downloaded. (Wolff Springs addresses this in their FAQ section.) This issue has been debated on other forum, with a lot of engineers involved and offering evidence. (Some metallurgists, engineers very familiar with metal characteristics, often participate.)

For long-term storage, downloading a round or two might prolong mag spring life. (And contrary to conventional wisdom, "working the springs" isn't the only thing that wears springs.) A spring kept fully compressed near it's elastic (design) limits will degrade faster than one NOT pushed/compressed that far. But not all mags, when fully loaded, are pushing the springs to or beyond their elastic limit. For a home-defense gun, I keep the mag fully loaded, and test it periodically at the range. For most of my other guns, the mags are kept UNLOADED. If I'm carrying, the mag is fully loaded.

 

.......i had some factory g19 mags that would only fit 14 rounds. I didnt care..

 

I noticed and have noted on here before the kel tec PMR 30 magazines would not load to full capacity when new. They also had issues with failure to feeds and other feed issues.

I stuffed them as full as I could and left them that way until the next range trip a few months later. Since then they have functioned with zero issues and are at full capacity as we speak.

 

Mine worked out of the box. I think in the last few years KT had some variability with these magazines with some hardly functioning at all, at least for a while. I bought my PMR in the fall of 2015. Kinda pissed me off when nutnfancy trashed the CMR over what was obviously magazine issues. Oh well, hopefully that means I actually might be able to get one sooner.

 

The mags are tricky to load I will admit. Takes a little practice to get them seated right but after the first range trip I have been able to blast away at will with zero malfunctions.

The only problem there is that burns on my arms don't heal quickly.

 

Can that be done for a Glock mag?

Yes. Might be a touch larger. The Glock mags are bigger overall than the metal double stacks.
