38 super vs 9 mm

Do you mean as in an open gun for IPSC? If so, stick with the 1911 size frames, and count on freeboring the barrel, and probably loading to a longer OAL.
At the end of days, you only gain cheaper brass, but usually wind up gaining headaches.

For running high pressure loads use the best brass you can get. I think the best is 9-23. I have never had a problem with it.the brass doesn't swell up like super and no silly rim to cause problems with. The down side is getting brass.
I used to load 9mm Major in the early '80s (170 PF, IIRC) Used IVI military brass. And experienced a few 'blow-outs'.
I believe .38 SuperComp is a rimless .38 Super, and that's the way I'd go being older and wiser these days.

I don't know why but the 9x19mm it was not really a pleasure for me, it's for some, but all these open gun had work on them by Gunsmith, on the other my current 38 super comp(2) work very well....built by a gunsmith
If you are going to run 9x23mm you might as well run the 38 super comp, it's a straight case and will cost you either less or the same
9x19mm is a cost saving, but also slow to reload on the press since the case a pretty much full.....so I can't crank them as fast as 38 SC.
The choice is either 2011 (S_I) or tanfoglio, there is at least one Eric custom that I know is running in 9mm, not sure how well, there is many 2011 in 9mm........

To hot rod a 9mm, the first big thing is a fully supported chamber. Then there is the work on controlling the unlocking and slide speed. This is usually performed with springs/mulitple springs.
A modified 1911 would be the most logical choice for a comp HG. I also think the XD could also work. The chamber and ramp/chamber support is the most critical issue in raising the pressure. The case itself is strong enough given what the US NATO loads are loaded to. However, reloading is not on their agenda.
The 9mm has been tweaked to make major, yes. Is the extra work worth it to save a bit in brass cost?
Someone like Armsco would be a good one to talk to on the pros and cons. Of course, there are tons of info and discussion on HG and IPSC forums.

Stick with .38S. The Supercomp or 9x23 is OK, but not worth the effort. The urban myth that the rimmed .38S feeds poorly is just that - a myth 
You can run major with 9mm, especially in a 1911 type action, but why? The brass is, at the end of a season, one of the smallest expenditures you have. Set up a 9mm case next to a .38S and have a look at the amount of rim there is available for the extractor to grab. Hmmmm At least one major manufacturer got caught when it was thought that a new extractor design that was excellent with .45 and .40 would also work fine with 9mm. Disaster 9mm in a regular 1911 is pretty decent with the old style extractor, well tuned, but a scoped gun has a need for much more precise ejection to clear the optics consistently. Can be done, but again, why?

Gunnar, I agree with you with respect to Canada.7x61 said:Stick with .38S. The Supercomp or 9x23 is OK, but not worth the effort. The urban myth that the rimmed .38S feeds poorly is just that - a myth
I've heard the argument in the USA that in a 28 round magazine; due to the extra rim width in 38S, a fully loaded magazine causes the top rounds to angle downward, wheras rimless rounds will remain angling up.
Whatcha think? Possible?
