What do you plan to use it for? .38 Super is a nice cartridge, but it's only at its peak when its used handloaded for IPSC-style competition where you want to 'make major' with as little recoil as possible. Otherwise, seek out a more common caliber. For self-defense, a .45 or .40 with decent hollowpoints is easier to feed, and is probably more effective; for plinking, you're going to get more volume out of 9mm; etc. Paras are good guns, but since they sell 14-round .45s, no point min/maxing your magazine capacity vs. power ratio with something obscure. Of course, again, unless you're shooting IPSC. Or this is a one-off Para someone's offered you or is on consignment at the gun shop, rather than looking at the entire Para product line, which forces your hand somewhat.
I thought after Port Arthur they got extremely tight with gun laws down there. Not to get off-topic, but what's the current situation?
