Makarov 1/2x28 tpi barrel.

[icebones]

Anyone know where I can find a replacement barrel for a 9x18 Makarov that is threaded for 1/2x28 tpi? The only ones i can find are 1/2x32 and I have a comp that is 1/2x28. Im trying to build a low recoil target pistol/carry gun for the wife, and she really likes the feel of the makarov.
