Accidentally dropping a mag from well design DBM system is a red herring- it simply is not a thing.
Stupid, poorly designed systems, sure. Lots of chassis and PRS bottom metal and mag latches are too long. However those aren’t field systems anymore than a 60x bench rest scopes are. The entire world is dominated by DBM’s and yet magazines aren’t littering the ground.
In any case, spare magazines are apart of the system and should be carried.
How do you lose a magazine? Do you also lose the ammunition?
Why is that people don’t “lose” pistol or AR magazines, but bolt action mags are some miracle smoke that just disappears?
Forgetting a magazine is just as amateur as forgetting the ammo- again, a red herring.
I'm not specifically referring to magazines popping out inadvertently, though as you pointed out there are some stupid, poorly designed systems that have that problem. I mean people fumble things and they get lost in powdery snow. I do quite a bit of work via snowmobile most winters (didn't get much winter this year) and every outing someone looses a scrench or a file, not to mention hardware if we're hanging signs. Heck I've dropped my keys just getting out of the truck and had to sift for them. Shit happens.
As to your Glock and AR mag question, are you claiming nobody has ever lost a magazine from their Glock or AR? That's ludicrous. I guarantee more Glock mags have been lost in history than revolver cylinders, and more AR mags have been lost than floorplates or fixed internal box magazines.
Actually now that I think about it when I first started carrying years ago I had an XDS in a crossbreed style holster (different brand) and the kydex didn't cover the opposite side of the ambi mag release. It was stupid. I had dining chairs, work benches and kitchen counters eject my magazine on more than one occasion.
I haven't had a lot of problems with my revolvers, tube fed lever actions, tube fed shotguns, or fixed magazine bolt actions, nor have I seen other people have many mag related issues with them (unless you count 303 rims in Enfields... which are actually DBMs...). But I have been witness at public ranges in the pre season sight in rush to people showing up and saying "I could have sworn the mag should have been in the case." I also vaguely remember as a kid showing up to a range with no mag for my 10/22 once and single feeding it.
I guess you can name call me as amateurish, and that's probably fair, but it doesn't change the facts.
Didn't Jake or his son walk away from a pair of Swarovski binos on the mountain or something like that in one of the early podcasts? I guess Jake's amateurish too.
I bet I can even find an example in this very thread:
Pretty funny not so funny story about losing your mags...I came across a guy in the mtns of idaho who traveled a long ways just to some how drop his mag in the snow.. he was on his hands and knees sifting through the snow all along his back trail.. it was after dark so I couldn't tell if he was crying or not.
Every decision is a compromise and for a fighting weapon the need for firepower obviously outweighs the possibility of losing a magazine. But for a big game rifle, there's no need for high volume firepower. All else being equal my preference would be for all essential components of my hunting rifle to be attached to my hunting rifle. It's not a hill I'm going to die on as evidenced by the Tikka I recently bought, but it would be my preference.
You might decide that the benefits of a DBM outweigh the risk of losing the mag by 1,000,000:1 and in your
opinion only idiots like me would ever consider an integral magazine, and that's fine.
But flatly stating that
there's not a single function in which a DBM does not outperform an integral mag isn't true. A detachable mag can become separated from the rifle, however unlikely or amateurish that may be, while an integral mag cannot.
Now I'm off to listen to Tuesday's podcast to learn what else I'm an idiot about...
