I own several guns in the 38super cal and one in the 9x23 cal. these guns are built on caspian and SVi frames. this ctg is an excellent defence round and the ballistics are impressive. I shoot open class ( racegun) the load i have worked up is pushing around 1400fpm 115gr IMR powder 7625. ONe guy said something about 9 largo the same length but more pressure, caution only shoot in supported barrels. rifle primers.

Need more info look up Duane Burns or contact Nowlin MFG they make this in a 1911 and they sell the best barrels

enjoy
