    I have a retailer I do smith work for he got a Walther PPQ it came with 15 round mags.
    He wants to sell it but due to NY law he can not sell the mags intill they are adapted to take 10 rounds only.
    Walther tells me that they will have 10 round mags available in 6 to 8 months(maybe up to a year) they are being made as we speak.
    I know a couple of ways to do this but I would like to see how others do it.
    When you "plug" a mag. do you use wood or plastic?
    Do you fit the plug so it floats inside of spring?
    It is a 9mm but walther says that only PPQ mags will work that any others wont fit.This doesn't sound right why another mag does not fit.Like the PPK.
    Are there any after market restriction kits to do this with?
    This is a new gun it hasn't been on the market that long.
    Any ideas?
    Thanks in advance for you help!

    The PPK has completely different dimensions, and why in the world would a .380 magazine function in a 9mm?

    Anyway, P99/SW99 magazines work in the PPQ, as well as Magnum Research Baby Desert Eagle mags. ProMag also makes 10rd magazines for these guns, although quality can be spotty.

    Thanks for the info.When I said like a ppk I was referring to that you can get other mags for it not that the PPK and the PPQ took the same mag.Or that they were the same cal.
    Do you ever plug mags?

    The way to go depends a bit on the law and the regulations (if any) to enforce it. If there is no need to permanently restrict the magazine, then a simple plug should be fine. But if the law requires, you might have to install a permanent block by welding or crimping, and possibly also cut the spring.

    Your dealer friend should be able to find out from the NYSP or the local LEA what is required so the ultimate customer doesn't get into trouble.

    I checked with the sheriffs and state police and this is there anser.
    "A magazine in the state of NY can only be able to hold 10 rounds"
    When I asked about altering a large cap mag to only hold 10 rounds I was told the same thing.
    When I asked if the change had to be permanent I was told the same thing!
    So allot of help they were :rolleyes:
    So I will tell the retailer just to buy after market mags or wait for the 10 round ppq mags to come out.
    Thanks jim

    That sounds about like an answer you'd get goofy!
    I've tried and asked a few questions as such down this way and usually, got a straight,
    no help sort of answer.
    Shame you couldnt make your project work just fine.

    Thanks Zane
    This question came up when he dropped off a couple of guns that he needed me to do some work on.
    I am not sure who he got the gun from because non of my distributors will send a gun here with max. mags.
    So it is his problem to deal with not mine.
    Not getting a straight answer from the local LEO around here is a ongoing problem.I normally here "What does the book say" but getting a straight answer is almost impossible.

    Here's how the game of Gossip works in NJ.
    (1) Citizen is confused by law and Attorney General guidance to legal firearms.
    (2) Citizen calls NJSP, who tell him to contact an attorney
    (3) Attorney calls NJSP, who says, "We don't know. Ask Evan Nappen, the attorney. He's the only one who figured it out."
    BTW, under NJ statute, a Marlin 60 .22 cal tube fed rifle is an assault firearm

    fudd, that guy with the Marlin 60 should have used the hillary defense. Its ok to break the law as long as you don't know that you are in violation of the law. Looks like he tried to say he didn't know that the gun held more than 15 rounds, when he should have said, as hillary would have, when did they change the law? i didn't know i couldn't have 17 rounds in it. The gun was made to 17 rounds i just thought it was legal! That's my stance too if NY gives me any crap about my Marlin holding 18 rounds! Yea i know another Zombie thread brought back.

    Since this post came up in 2012 things have changed. (In NY) You CAN block a mag to ten and it is legal. There are a few ways they let you do it. You do not have to block tube fed .22s.
