Either the CZ PCR or the Makarov (East German Military model)
The PCR is light, with a great capacity and unlike the P0-1 has no light rail which to me is unnecessary on a gun that size.
The Makraov's used to be a great deal $ wise but the mak is simple, rugged and goes bang everytime. Caliber is better than a 380 but not as good as a 9mm luger. Ammo is cheap.
