I am in the process of building an unlimited gun for IPSC competition. I am going with 9mm to take advantage of the cheap brass. The Super and its immitators can develop higher velocities at lower pressures than the 9, but do you really need it? It would be a lot cheaper to stay with the 9 if it could satisfy your needs.buddy_fuentes said:Monkeyman, did you ever convert your 9 mm to a Super? If so did it work and what did you use for magazines?
My son and I are thinking about buying two P-18 9mm's and converting them to 9x23 or .38 TJ. We would keep the 9 mm bbl. and buy new match barrels and have them fitted to the pistols. We need to look at the issues we may run into with magazines. We think it would be fun guns. I already have a 9x23 and he has a .38 Super, but we like the idea of a high cap and a hot cartridge.
Looks like he said he's building an open class gun. 9mm is major in open as long as you make the power factor. .40 is the min bullet dia. for limited.stansdds said:Only problem with 9mm is that it is classed as a minor caliber in IPSC/USPSA, so hits outside of the A zone score one point less than the same hit with a major caliber. The trade off is speed. Most people can fire the 9mm faster than other calibers due to the 9mm's soft recoil impulse.
