In New York state it is illegal to have a magazine that holds more
than 10 rounds (aren't we lucky?).. I w3ant to get a Zastava EZ 9
(9mm) and I have a mag I would like to modify. My plan is to cut 2
coils off the mag spring and insert a block between the mag spring and
mag bottom. Does this sound workable or does anyone have a better
idea?
Thanks.

Why cut the coils at all
After all the mag spring is designed to work with the equivalent of your
(intended) block.

Don't cut it. Your magazine is designed to work with the full spring. Only
difference is, that the spring will act like there's five rounds left when
it's actually empty. Full force feeding.

It is not illegal to own a magazine that holds over 10 rounds as long as
it was made prior to the AWB which never expired in NY.


"New York's version of the law is very similar to the Federal version,
but New York's version does not have a sunset provision. According to
the laws of the State of New York, a magazine with a capacity of more
than 10 rounds manufactured after September 14, 1994 cannot be legally
possessed by anyone other than a law enforcement officer. A provision of
the Federal law required the date of manufacture to be stamped on every
newly manufactured "large capacity" magazine. Because that requirement
is no longer in effect, the New York magazine ban becomes potentially
unenforceable except with respect to those magazines manufactured during
the ban and marked according to federal regulations then in effect.

NYS Penal Law � 265.02(6) makes it a class D felony to possess "a large
capacity ammunition feeding device," which is defined in Penal Law �
265.00(23) as "a magazine, belt, drum, feed strip, or similar device,
manufactured after [September 13, 1994], that has a capacity of, or that
can be readily restored or converted to accept, more than ten rounds of
ammunition." Possession of unmarked "large capacity" magazines made
after the sunset of the federal ban thus subject New Yorkers to felony
charges. Police and prosecutors may be able to determine actual
manufacture dates of seized magazines from information not generally
available to consumers, such as the dates of magazine design changes and
parts assembly numbers. The New York ban thus leaves possessors of
unmarked post-ban magazines at risk of felony charges since they may not
know the magazines were manufactured post-sunset and not pre-ban.
However, the prosecution must be able to prove that the subject in
possession of the magazine had knowledge that it was in fact a post ban
magazine."

Why not just insert a "plug" in the magazine? Same idea as a plug in the feed tube of a shotgun.

I remember doing this in the 1960's for an M1 Carbine when the PRK mandated 10 rounds maximum. I think that since then we have removed the plugs restoring the mags to 15 round capacity.

Would such a modified magazine be acceptable to your local agents of The
State?

Would they take your word for it?

Would they take your word that it couldn't be immediately restored to
an evil 11 round capacity?

I know about the New York State Penal Law - I've had my Pistol license
for over 50 years.

It was my intention, once I have made sure the mag would hold only 10
rounds, was to crimp the mag base to the mag body, have a welder tack
it down and then take it down to the nearest Sate police station and
have them look at it. Crimped and tack-welded should make it
impossible to re-modfy to more than 10 rounds without destroying it.

I emigrated from NY to a free country (Tennessee) about six years ago,
but at that time "pre-ban" full capacity magazines were allowed. In
other words, if it didn't say "law enforcement only" on the magazine,
it was legal. Has this changed?

If the New York state police are anything like the Maryland state
police, you'll get wrong information.

There are several make/models of this gun under other names. It seems like it would be easier to just buy a factory marked 10 round magazine. Example

Unless you enjoy having conversations with uninformed LEOs...

My source at the local sheriff's dept doesn't believe that this would meet
CA requirements. (But might be OK in other states).

He recommends modifying the magazine in such a way that it is not easily
reversed.

Yes. You need a 'permanent' modification.

I would use JB weld to glue the block to the base plate, once you know
exactly how big to make them. Use the JB Kwik weld formula, it's WAY
easier to use. It comes in a package with an orange background. The
Walmarts here carry it.

Once done, the modification sure looks permanent.

All you need is a new base plate, to return the magazine to full
capacity, when you finally escape from the PRK.

It might even be possible to remove the block from the base plate, with
a hammer and chisel. JB weld is tough, but every glue has a breaking
point.

The modification must be permanent - not undo-able - to pass with NYS.
If you don't destroy the mag trying to return to plus 10 capacity, it
would never get approval.
So far, I have found the LEO's in the Pistol Permit Bureau to be
reasonable people.

Heat the magazine/plug with a propane torch. It will come loose. Though
the magazine wont be pretty after you are done..it will still work.
Remove the magazine spring and follower first..of course.

Unless you enjoy making work for yourself, it would be far easier to simply purchase a CZ 10 round magazine - these fit the EZ 9. See
