One time I was looking at something in a store which had two mags were blocked to 15 rds from 17 or 19. I asked the guy 1)how can I prove they could hold only 15 rds because they had 19 little holes? 2) How can I prove the modification is perm?

His anwser to 1) was to put ammo into the mag to show it can only hold 15 rds. That means I need to have ammo with the mag all the time.

He avoided to answer 2).

So far I don't have any modified mags.

What is your take on this?

I'm personally not into using 'blocked' mags. My belief is that if the manufacturer don't make it, I don't use it. What particular weapon are you referring about anyway?

Might have been a CZ SP01. I agree with you. It is not worth the trouble may come up.

Antz, the CZ P-01, compact version, comes with 14 round mags. I had it the other night. I forgot you were interested, I wouldhave offered it to you to try. If you come down again, I will make sure I have it for you.

Thanks. I did see one in store after you told me. The particular one did not have night sights so I did not buy it. But it was very nice and getting expensive. $650

I know it's not official legal advice, so take it with a grain of salt, but my FFL said that "permanent" means that you will need tools and serious work to reverse the modification. So in a hypothetical gunfight with the cops, you couldn't just put on your evil flash hider with just your fingers.

Its perfectly legal to block a shotgun with a dowel in the tube mag to comply with ammo capacity hunting regulations, which is in no way permanent, but the same technique isnt legal for a magazine? Seems to be a bit of a conflict. You would think the shotgun technique would set a precident.

shotgun is covered by game laws, but NJ is flawed in any and all logic.
