joshua Posted April 16, 2004 Share Posted April 16, 2004 I've been getting lots of different answers on which hi-cap frame is best to build a 9x19 open gun with. It's probably not the frame but the magazine that is more important in feeding reliability. Most have said SV or SxI with spacers in the mags, some swear by their Para O. My Caspian mags are temperamental, I get lots of nose dives due to the length and the tapered round doesn't really stack very well. josh Link to comment Share on other sites More sharing options...
Singlestack Posted April 16, 2004 Share Posted April 16, 2004 I do not think it would matter as far as SVI or STI. You can use both mags in either frame. It's probably not the frame but the magazine that is more important in feeding reliability. Link to comment Share on other sites More sharing options...
Alan Meek Posted April 16, 2004 Share Posted April 16, 2004 Josh, Are your Caspian Mags the actual Caspian mag or are they the Craig aftermarket mags? Alan Link to comment Share on other sites More sharing options...
warpspeed Posted April 16, 2004 Share Posted April 16, 2004 I run SVI mags in my 9x19 guns w/o any problems at all. Link to comment Share on other sites More sharing options...
Chriss Grube Posted April 16, 2004 Share Posted April 16, 2004 The SV mags work 100% w/o the spacers. The STI mags won't feed standard length ammo w/o the spacers. Nice thing is the SV mags will work in the STI. Link to comment Share on other sites More sharing options...
joshua Posted April 16, 2004 Author Share Posted April 16, 2004 Josh,Are your Caspian Mags the actual Caspian mag or are they the Craig aftermarket mags? Alan Alan, My mags are original 1st gen Caspian hi-cap mags except for two 170mm+ Craig mags. I did try feeding by just cycling through 9x19 rounds and I was getting nose dives. Maybe the length on the rounds were too short and may need to seat the bullets to max. Both my open gun feeds 38 supercomp 100% because I tuned the mags, even the Craig mags are 100%. Is there anything I need to do to my Caspian mags to make them work for 9x19? I'm basically looking at a new top end in 9x19, but if it doesn't work I'll go the extra mile in getting a different frame. Thanks for all the inputs guys. Keep 'em coming. josh Link to comment Share on other sites More sharing options...
old shooter Posted April 17, 2004 Share Posted April 17, 2004 What length are you loading. Try some 1.16 and see if that helps. They feed from my sti and svi mags without any modification (to the mags) Mike Link to comment Share on other sites More sharing options...
Alan Meek Posted April 17, 2004 Share Posted April 17, 2004 Josh, I am loading 9x19 to ~1.145 oal. This length seems to work. I have played with lengths out to about 1.160 Alan. Link to comment Share on other sites More sharing options...
joshua Posted April 17, 2004 Author Share Posted April 17, 2004 I just put a caliper on some of the 9mm loads I had cycled through the gun. They were 1.165 OAL, 125 gr fmj. I wonder if loading up to 1.2 can have enough case to hold the bullet reliably? I did try cycling some rounds again and I have some of my mags able to be 100% reliable, not many though. I'm gonna take a closer look and see what's the difference between those mags and the once that don't feed 9x19. josh Link to comment Share on other sites More sharing options...
Chriss Grube Posted April 17, 2004 Share Posted April 17, 2004 I have loaded out to the old 1.250 in 9mm with 125's. Not much bullet in the case but they worked. I'm loading to 1.190 now. Link to comment Share on other sites More sharing options...
Harmon Posted August 8, 2004 Share Posted August 8, 2004 loading longer than 1.16 really depends on bullet design and shape FMJs dont really work that well. MG JHP 124s work good. Link to comment Share on other sites More sharing options...
