Demetrio Posted December 16, 2011 Share Posted December 16, 2011 (edited) Well, I shoot Production and that's the problem: I cannot import a 9mm pistol in Brazil (9x19), but I can import a 9x21 instead. On the other side, there is no how to buy 9x21 brass here in my country, but I have a huge amount of 9x19 cases for reloading here. So I was wondering: would there be any problem by shooting 9x19 cartridges in a 9x21 barrel? How about chances for malfunction by doing so? Thanks, Demetrio.

DWFAN Posted December 16, 2011 Share Posted December 16, 2011 Can you buy a 9x21 pistol, and swap the barrel to a 9x19 ? What gun are you looking at buying ? (for reference of how easy it would be to switch barrels) Quote Link to comment Share on other sites More sharing options...

DWFAN Posted December 16, 2011 Share Posted December 16, 2011 That should be switchable if it is legal to do so. Quote Link to comment Share on other sites More sharing options...
Demetrio Posted December 16, 2011 Author Share Posted December 16, 2011 (edited) That should be switchable if it is legal to do so. But the problem remains the same: if I cannot import a 9x19 pistol here in my country, I won't be allowed to import only the barrel either.

DWFAN Posted December 16, 2011 Share Posted December 16, 2011 Hmm.. bummer. It's not recommended since the round needs to headspace on the case mouth. http://www.brianenos.com/forums/index.php?showtopic=127757 I wonder if anyone has ever tried to fit a 2mm spacer into the chamber. It would have to be a very precisely made piece and fit very tight.. Quote Link to comment Share on other sites More sharing options...
want2race Posted December 16, 2011 Share Posted December 16, 2011 Spacer might be tough. That will also give a long leade length. Would be easier to fabricate brass. With enough time and money I'm sure the chamber could be drilled out and a completely new 9x19 chamber inserted. I've seen two piece barrels before.

DWFAN Posted December 16, 2011 Share Posted December 16, 2011 Thinking outloud.. The 9x21 and 9x19 have the same SAMMI OAL, so the lead shouldnt vary to much right? If so, you can always load longer in the 9x19 case.. right? Quote Link to comment Share on other sites More sharing options...
Demetrio Posted December 16, 2011 Author Share Posted December 16, 2011 Can I drill a 38 Super Auto case to the 9x21 lenght and use it for the purpose I want? Are the other dimensions of the 38 Super Auto and 9x21 cartridges compatible? Quote Link to comment Share on other sites More sharing options...
want2race Posted December 16, 2011 Share Posted December 16, 2011 You would be relying on the extractor to hold the cartridge for the FP to hit the primer. Having the same OAL doesn't change the leade lenght. The rifling gradually starts after headspace ring. If the x19 goes off in the x21 chamber the bullet will have quite a bit of freespace before hitting the lands. Gas will be going around the bullet as soon as it leaves the case. Here's another thought. Cut down 5.56 brass. Although if you can't have 9x19, you might not be able to have .223/5.56 brass either. The diameters are closer than the length difference between 19mm and 21mm. The cut down 5.56 case would fit the 9x21 chamber like .40 in a stock Glock barrel (just a tad loose). Plus, once you shoot them, they'll expand to the chamber anyway. The difference is around .015". Easy, no. Easier than rechambering for 9x19 though. No match would be a "lost brass" match for you...LOL Quote Link to comment Share on other sites More sharing options...

Some folks have shot thousands of 9x19 in a 9x21 gun with no issues at all. It is however headspacing off the extractor and could cause problems down the road.

skeeter Posted December 16, 2011 Share Posted December 16, 2011 back in the 90's a buddy of had a 9x21 pistol, and with brass being costing so much he'd use9x19 all the for practice. he shoot at least 10 times as many 9x19 rounds than he did 9x21 and never has a problem. i'd said go for it.

38supPat Posted December 16, 2011 Share Posted December 16, 2011 I have a friend who cuts down .38 supercomp to 9x21 length and aside from needing to change to load to suit the different internal capacity it seems to work pretty well. I wouldn't recommend doing this but if you have few other options it may be something to try. Quote Link to comment Share on other sites More sharing options...
Glk21C Posted December 16, 2011 Share Posted December 16, 2011 A friend of mine down in Florida was sponsored by EAA back in the early 90's. His open gun (EAA/Tanfoglio) had a 9x21 barrel, he shot and continues to shoot 9x19 through it. Well over 100,000 rounds so far, he's had no issues. Even if you had to replace the extractor, on the Tanfoglio's, they are super easy to do and very cheap. Good luck Quote Link to comment Share on other sites More sharing options...
Al Capizzo Posted December 16, 2011 Share Posted December 16, 2011 I've shot quite a bit of 9x19 major through a Tanfoglio 9x21 barrel, I've never had any issues. Yes, it is headspacing with the extractor, but I wouldn't be surprised if that didn't happen a lot anyway, despite the way it is "supposed" to work.

david s Posted December 16, 2011 Share Posted December 16, 2011 I sent my 9MM barrel in my Match and had it reamed to 9x23 Winchester. Cost $50.00 here in the states. Winchester still makes 9x23 ammo. If i understand the law about owning a 9mm chambered gun in your country and If a 9x21 is legal the 9x23 will be also. The Match shoots 9x23 like the factory made the gun -- using 38 Super mags. I'd have to try shooting 9mm in the gun first. Quote Link to comment Share on other sites More sharing options...

Jody Waring Posted December 18, 2011 Share Posted December 18, 2011 Like Al mentioned, I know plenty of guys that have shot x19 in x21 barrels with no trouble. Another viable option would be if you reload, order the gun in .40 and download it down to minor. Ipsc has the 15 round limit now, so I expect you can get 15 rounds of .40 in the stock 3? Just a thought. Quote Link to comment Share on other sites More sharing options...
Demetrio Posted December 18, 2011 Author Share Posted December 18, 2011 (edited) Thank you all for the replies. I think I have how to get a good amount of 5.56 brasses over here and cut them down to the lenght of 9x21, like want2race suggested. Jody, I don't like the idea of shooting Production with .40. I think 9mm is the perfect caliber for this division, but, like I said before, there is no way to import a 9x19 gun here in my country, so I think a 9x21 will be the way to go. Cheers, Demetrio.

giova22 Posted January 1, 2012 Share Posted January 1, 2012 Hello Demetrio I shoot about 10000 9x19 in my 9x21 Glock 17 without any problem or failure. Best regards Giovanni Quote Link to comment Share on other sites More sharing options...
Jody Waring Posted January 1, 2012 Share Posted January 1, 2012 (edited) Are you getting any erosion in the chamber at all? If you have fired that many rounds with no problems, I'd consider trying it myself as I have two 9x21 open guns, and brass is hard to come by. The only reason I mentioned minor pf .40 as I have heard of guys doing it with fantastic success and have developed some very soft shooting loads.

giova22 Posted January 1, 2012 Share Posted January 1, 2012 I shoot leadfree 9x19 ammunition in my 9x21 Glock. The bullet is only 89grs and really fast (1400 pfs + or -) but i cannot see erosion. 9x21 brass here in Italy is the most common type and inexpensive.

Jody Waring Posted January 1, 2012 Share Posted January 1, 2012 That load likely has a decent sized powder charge and if it was going to cause wear you would have experienced it by now for sure. Quote Link to comment Share on other sites More sharing options...
giova22 Posted January 1, 2012 Share Posted January 1, 2012 Yes, you are right. The load is really hot but it's not a problem for my Glock. A friend of mine used the same ammo on a CZ75 SP01 and broke the extractor after about 2000 rounds but we are not sure is due to ammo. If you need 9x21 brass i can search them for you, they are really cheap here. Quote Link to comment Share on other sites More sharing options...
