Dick Flanagan Posted November 12, 2006 Share Posted November 12, 2006 Is the guppie-bellied phenominon only applicable to 40 S&W brass or to all Glock-fired calibers? Dick Flanagan Link to comment Share on other sites More sharing options...
ParaJoe Posted November 12, 2006 Share Posted November 12, 2006 To my knowledge it applies to all Glock fired brass. I have 9mm, 40, and 45 fired from a Glock that are bulged. Joe Link to comment Share on other sites More sharing options...

Joe OK, that's what I needed to know. Thanks ParaJoe. Dick Flanagan Link to comment Share on other sites More sharing options...
.40AET Posted November 12, 2006 Share Posted November 12, 2006 There are other guns out there that have unsupported chambers. I get a ton of guppie-bellied brass that does not have the square striker mark on the primer that a Glock makes. Link to comment Share on other sites More sharing options...
TBF Posted November 12, 2006 Share Posted November 12, 2006 My experience has been that the 40 Glock brass shows alot more of the belly than 45 or 9 brass . Just .02 from casual observation. Travis F. Link to comment Share on other sites More sharing options...
Harmon Posted December 19, 2006 Share Posted December 19, 2006 40 is the worst...and its not that bad with some of the newer brass. Speer and PMC seem to be the worst offenders. WInchester and Remington seem to be tougher these days. Harmon Link to comment Share on other sites More sharing options...
AZ38super Posted December 19, 2006 Share Posted December 19, 2006 I owned a couple Glock 17's and never had a problem with the brass from them. Link to comment Share on other sites More sharing options...
revchuck Posted December 19, 2006 Share Posted December 19, 2006 (edited) I owned a couple Glock 17's and never had a problem with the brass from them. Problems only seem to show up when reloading Glocked brass using standard dies for use in aftermarket match barrels. Using such ammo in factory barrels, even non-Glock ones, seems to work fine. This is my personal experience in 9x19 and .40 S&W; I've probably reloaded Glocked .45 ACP brass too and just don't know it, and haven't had problems in my .45 ACP bottomfeeders with match barrels (USGI and BarSto).

David Sinko Posted January 10, 2007 Share Posted January 10, 2007 I put about 10,000 rounds through my Glock 21 which I bought used with a Bar-Sto barrel. I liked that Bar-Sto because it could shoot lead but I have learned to never use it in a match. It never ever failed to feed any cast bullet but sometimes it would fail to fully chamber the cast bullet and occasionally the jacketed ones too, even after they dropped into the chamber checker. I do not think that the factory barrel for my 21 is hard on brass. My 35 is a different story though. Fired brass gets ugly real quick and I load them only about a half a dozen times before I no longer bother to pick them up. My 35 is a game gun only and I run only one load through it. It never lets me down. That chamber will feed some pretty ugly rounds and that polygonal rifling is very forgiving with plated bullets no matter how badly they've been abused during the loading process.
