Beveling magwell opening in Production?

Recommended Posts

I saw one real old post on this ... about 5 years ago. Can I "cut"/"bevel" the INSIDE edge of the opening of my magwell area on my CZ Shadow for Production? I know the SP01 version (full dust cover) has this area beveled from the factory. I thought there was a more recent post that confirmed this was indeed allowed... but of course I can't find it.

Does this help?

22.4 Magwell opening The longitudinal (front-to-back) dimension of the

opening may be more than 1/4” greater than the corresponding dimension of a magazine. External flaring

remains PROHIBITED.

Now that I have read that paragraph carefully did they omit the word "not" after "may"?

Ha! The way I read that, there is no limit on the longitudinal dimension :surprise:

I don't understand why beveling the magwell wouldn't be legal.

It says May, not May Not.

In addition there's the NROI ruling on plastic plugs in glocks.

Qestion: Can I now insert the plastic plug in my Glock and will it be legal for Production division?

Answer: The plastic plug that fits flush with the heel of the grip is allowed, like the Jentra plug. Plugs that extend below the heel like the Scherer polymer slug plug or other similar models are not allowed. Metal, brass or the Seattle Slug plugs are not allowed either.

If it's good enough for the glocks it should be good enough for all guns. In my opinion they're both internal modifications and therefore should be legal.

As I understand D4 22.4 you can bevel inside the magwell to the front or to back, but you can't bevel towards to the sides. Post #4 above though is making me doubt my understanding of the rule.

Now that I think about it, if the OP is talking about beveling the side to side width of the gun, I think it would be illegal. But if he were to bevel the front to back it seems that it would be legal. That's my interpretation anyway, which doesn't matter that much.

I was talking about putting a slight "radius" all the way around the opening to get rid of the sharp edges. I guess there still seems to be some confusion about this.... not sure what to do. It sounds like Corey got the answer I was looking for though.

I had a long talk with John amidon about this. It's pretty much a 1/8 inch from the magazine allthe way around the magwell.

Reposting, as this is THE answer. 1/8" all the way around the magazine, that means 1/4 inch total.

You can't go too much in the rear because of the hammer spring plug. But you can take quite a bit off the sides and front and still be under the 1/8" limit.

Pics needed....Corey....LOL

Anyone have Amidon's answer to this in writing somewhere? I plan on shooting some major USPSA match and want to have documentation with me. Thanks!

Would an email work for you? I hope not.

If it doesn't appear in Front Sight (as a Clarification) or on USPSA.org (as a Ruling), it wouldn't really be worth much. If someone waived an email from JA at me at a match, I'd be very interested in what it said but I'd still be compelled to ask, "Where was that publically published?"

**Mr. Amidon has been burned a number of times by people taking and promoting email responses as 'USPSA Gospel', when in fact they are not. Many folks have also taken to describing John's more recent replies to email questions as "Sphinx-like". I suspect the two are linked.

Ok, understood. Would any care to specify where this may be posted? i don't keep my Front Sight. I'll look on USPSA.

Rules are rules- that I understand- but I will say sometimes they make me crazy! The SP01 has the mag wells beveled from the factory.... My std Shadow didn't and now I could have just made a cheap open gun? Great...

I do have a email laminated in my range bag stating that I could have my 75 beveled 1/8" all the way around the opening. It's inthe rule book as such but I wanted clarification as the wording is some what lawyer like.

Oh and that email is from John. You don't have to believe that but you do have to follow what the rule book states and the email just clears that up.

Are you referring to this section as in post #2 above? Damn that's clear as mud... but I'm good with it! rolleyes.gif

•No magwell attachments or external flaring of the

magwell. The lateral width of the well may not be

more than 1/4" wider than the lateral width of the

magazine.

I was an airdale not a swabbie but I thought there was a difference between longitudinal and lateral. Doesn't one mean length and the other width?

For the record post #2 does not say that. I guess it is a typo but it is a pretty damned important typo to go left unfixed or ignored.

Well John A is the USPSA contact for this. I emailed him.

He replied with:

"APPENDIX D4 - Production Division (Contd.)Special conditions:

22.4 Magwell opening The longitudinal (front-to-back) dimension of the

opening may be more than 1/4" greater than the corresponding dimension of a

magazine. External flaring

remains PROHIBITED."

Ugggh.. this also has the "typo"

I don't think Front Sight is any different from an email.

I agree about the rulings published on USPSA's website, but I do think the clarifications published in Front Sight carry more weight than an email. It is, after all, the official journal of the USPSA.

I was taught long ago that the rulings on the website are implemented when an actual error or discrepancy exists in a rule, or when a change is agreed by the BoD. The clarifications published in FS are intended to help bring understanding to properly worded, yet widely misunderstood rules.

I believe you've also said as much in the past. Have you learned something new in your time on the Board?
