Hi-Cap Magazine Conversion?

[FullMetalJacket]

I own lots of pre-ban hi-cap magazines. I just got to thinking: for my Glock 17, would it be legal to "decommission" one of my 17 rounders in favor of a new 33 round magazine? How much of the 17 rounder would I have to "recycle?"

[Linh]

no you can't make a new 33 round mag. You can't get rid of two of your 15 round mag and convert it to a 30 round mag.

If this isn't what you're asking then I have no idea what you are talking about.

Yes, that's fine. The follower and baseplate can be reused. Nothing wrong with making a preban high cap mag more high capacity'er..

[bohoki]

well lets say hypothetically you replace your 17 rounders innards with the 30 rounders spring and follower

then thought hmm this spring is too tight i think i'll replace the body with the 30 rounders


you started with one large capacity feed device and ended with one lcfd


the weird scenario happens if say you had a glock 19 magazine and now all of a sudden you created a magazine for your glock 17

But, it still works in a Glock 19.

Rebuilding the 17 rounder of course, with parts from the 33 rounder.

As long as it is a progressive rebuild, and you don't end up with a mag for a different gun, or with two mags or something like that, I think you are good to go.

Of course, you can do whatever you want. If someone with the law questions it later just explain it, they will certainly understand, no worries.
I am thinking it's like the IRS, claim what you want as you only have to explain it if you get audited. If they buy your convoluted reasoning no harm no foul, if not it will cost you a bit of money and time.

Capacity is not an issue. As long as you don't end up with more Hi Caps then when you started. Nothing in the law states you have to use old parts, but if you feel you need to then use the floor plate or follower. There are a lot of good threads that have covered this. Hope this helps.

It's legal and that should be the end of the discussion.

From another thread.

You already had a hicap mag you legally owned/acquired in CA (pre 2000).
You increased its capacity from 12 to 14.

There's only one level of "high-capacityness" (over 10rds), and you already legally had it: you can't make it "more high capacity" from a legal standpoint.

There are no additional levels or tiers of hicap status: the threshold has already been crossed.

You could have done this before or after 2000 and it would not have been relevant.

A high capacity ammunition feeding device is just that. If you have one and modify it to fit a new gun - but it still functions in the old gun for which it was designed and was legally acquired/possessed - that's fine.

I would add that destroying the old functionality to make it work in a new gun could risk being regarded as manufacturing/creating a new hicap mag.

Talk of hi-cap mags makes me wish I would have gotten into guns back then.

Question for the masses here.....how does anyone know if you have hi-cap mags? Are they supposed to be registered?

"They" don't, and no.
