Talk:9×21mm

Why the ban?

I'd love to know why Italy has banned the 9mm Luger... —The preceding unsigned comment was added by 66.129.224.36 (talk • contribs) 02:10, 25 February 2007 UTC.

As would I. A source for that would also be nice. The 9mm Luger article (and even the Italian version of that article, via Babelfish) says nothing about that. — Redxiv 05:00, 20 May 2007 (UTC)

Italy bans the civil use of their military service cartridges like the 9x19mm Parabellum used by Italy and other NATO countries.--Francis Flinch (talk) 18:29, 22 October 2008 (UTC)

Why does it not state what country they are banned in on the main page. Assumption is that they are banned everywhere for civilians by anyone visiting the page. Also shouldn't it be sourced. - 74.42.179.83 (talk) 03:31, 20 October 2013 (UTC)

During World War II the Allies parachuted many Sten and Thompson SMGs behind the German lines in Italy, to help the guerrilla in the fight against the Nazi-Fascists. The partisan themselves captured quantities of MP-40 and Beretta M38. After the war, the government collected and seized most of these weapons, but it is likely that many were hidden and were not handed over to the government. Therefore the ban of the .45 caliber ACP and 9x19mm cartridges. — Preceding unsigned comment added by Alessandro Roverano (talk • contribs) 23:29, 9 December 2019 (UTC)

Ballistic Energy for 9x21 IMI over *1000) Joules???

I've been comparing the ballistic performance if the 9x21mm to the 9mm Luger, and by convention of the article, the ballistic energy of the two should be more or less the same. But according to the ballistic energy data table in this article, the 9x21 packs a whopping 1041 Joules of energy for a 124 gr FMJ travelling at 360 m/s. Comapre this to ~484 J for 9mm Luger 115 gr FMJ at 1180 ft/s (~360 m/s) and even the .45 ACP 185 gr JHP at 950 ft/s (~290 m/s) 371 ft·lbf (~505 J). This is a major miscalculation.. please see to it ASAP, thanx.

error

in italy is banned only 9x19; 9x21 is the most used cartridge, i delete the wrong note --79.6.48.175 (talk) 22:09, 22 June 2013 (UTC)

I’m sorry to say it but this article is poorly written for English speaking people. I’m reasonably confident the writer is not an English speaker. I would help with grammar and construction, but I don’t know enough about the subject; so any changes I made could produce inaccuracies.

The problems are indefinite antecedents and run-on sentences. The matter troubles me because I am interested in the subject and would like to understand the 9x21 better. Cadillac84 (talk) 11:31, 11 May 2021 (UTC)
