Yar Posted May 14, 2003 Share Posted May 14, 2003 If you were to build a open class 357 sig Glock, and the ammo made power factor. Would it qualify for major in open division, now that 9mm major can be scored major? Link to comment Share on other sites More sharing options...
Carlos Posted May 14, 2003 Share Posted May 14, 2003 Yes, it would qualify in Open as long as it made the 165powerfactor. BTW, Sig has always been allowed in open since it is not "9mm" or 9x19. The so-called ban on "Open 9" applied only to 9x19 loaded to old, then new-major and under a certain OAL (a length that coincidentally allowed it to fit in 1911 magazines but not fit in many foreign make guns like the Glock). Glad that the BOD directive has been rescinded - it was about time considering the number of off the shelf 9x19 loads that can meet new lower major.

Flexmoney Posted May 14, 2003 Share Posted May 14, 2003 Yar, It is legal. But, before you spend the $$ consider the mag capacity. It's not enough to make me happy. Link to comment Share on other sites More sharing options...
Carlos Posted May 14, 2003 Share Posted May 14, 2003 Good point Flex! Yar: you only have 170mm to work with and the 9x23/38 Sup/TJ/9x21/9major crowd can fit 28 to 29 rounds in that same space. In shorter mags of equal length, the 9s will generally have an advantage as far as capacity. You might want to trade the .357 for something else as the basis of an open gun.

Flexmoney Posted May 14, 2003 Share Posted May 14, 2003 Yeah...I run into too many 24 round stages to make me comfortable with the reduced capacity of 357/40 in a 170mm tube. I think 40 would be easier to load than 357 anyway (easier to get and use brass). But...I'm drifting. Yar, it is legal. Link to comment Share on other sites More sharing options...
ErikW Posted May 14, 2003 Share Posted May 14, 2003 Beven Grams does pretty good in Open shooting a .40, same mag capacity as .357 SIG. BTW, go 9x21 if you want to shoot Open in a Glock! Link to comment Share on other sites More sharing options...
Yar Posted May 14, 2003 Author Share Posted May 14, 2003 I'm just cuious. I do not own a .357 sig and was just wondering on it's suitability for a open gun platform. Which model glock would be the prefered platform for 9x21? The glock 20? Link to comment Share on other sites More sharing options...
ErikW Posted May 14, 2003 Share Posted May 14, 2003 17 or 34 (9mm breechface) for 9x21. You could even have a stock barrel reamed to 9x21 for a few bucks. I shot with a couple Open 9x21 Glocks on my squad at Area 1. I think they were 17s. Link to comment Share on other sites More sharing options...
Vince Pinto Posted May 14, 2003 Share Posted May 14, 2003 Yar, It's not just a matter of calibre. Your ammunition must also comply with the minimum bullet weight to qualify for Major in Open Division (IPSC 120 grains, USPSA 112 grains). Link to comment Share on other sites More sharing options...
Flexmoney Posted May 15, 2003 Share Posted May 15, 2003 Yar, The 9x21 or 9x19(Major) can be done with the small frame Glocks. There are 170mm mag extensions that will get you 28 rounds or better. Major Open can be done with 40 or 357 in the small framed Glocks also. You just won't have the round capacity advantage. The G20 would be the way to go with the 38 Super family (large framed Glock is needed for the OAL of the Super family of cartridges), but nobody makes 170mm mag extension for them. (The G21 is considered a poor choice because of the width of the 45 breech face.) Link to comment Share on other sites More sharing options...
