I down load my 32 rd 9mm mags to 30 that just makes the counting easier
Is that the idea behind teaching slapping the mag in after insertion?
Mine were/are used the same way mostly.No. Because I don’t think own any 30 round mags. If I do, I don’t use them. My AR’s are used for hunting. 5 and 10 rounds. So I load them full and cycle one in the chamber.
Back when I had to use an M4 for a living, We always loaded a full 30 rounds in our mags and rarely/never had issues. I’ve seen a lot of people today sticking with the advice that you should only load up to two less than max (8 in a 10 or 28 in a 30) under the apparent assumption that a fully loaded mag will cause issues.
Does anyone do this, have you had issues with fully loaded mags?
If a magazine is topped off to full with 30 rounds and the springs won’t compress on a closed bolt enough to easily seat the mag, then is the mag defective? I’d say not. But could mag designers add a tad more length to facilitate 30 rounds and still allow spring compression? Sure, but then folks will cram another round in it.
I download by one as needed so I can seat mags easily while under stress without worrying if they will lock in. It’s that simple.
Spent 28 years in the Army, and I always fully load mine, because that's how I was trained. It's how I trained others too. Now, maybe they're teaching to download one these days... I don't know, been retired since 2009.
It does make the closed bolt tactical reload easier, but if you're doing one of those, it's during a lull anyhow, so you can take your time to do it right.
The real problem with magazines are the feed lips. Can't be too frugal, and not trash a mag when it starts screwing up on you. A magazine is a consumable item. Otherwise it will pop a couple out loose in the action when you seat the mag on an empty chamber with the bolt locked back. Then you hit the bolt release, and you've got yourself a first class double feed jam. I actually had my wife mail me a couple dozen of my personal mags on my last deployment to Iraq so I could fix mag related problems in my section, because the unit was stupid, and mobilized with a crap ton of old training mags. (Left most of them in theater for the next unit. Probably belong to some Haji now.)
I never did competitions for time like 3 gun matches, so I don't care how they do it. .
Actually, yes I do. All of mine are fully loaded with a rd chambered. The only time I put a new mag in with open bolt is when I've just emptied a mag. All of them have 30rd mags except my coyote gun and my night vision gun, these usually have 10rd mags.Hmm? No one does 30 + 1?
