for all yee that dont like the 9x19, its better than .380 and probably as good as9mmbrw lng. only trade off might be cost pr rnd. converting any weapon to another caliber can be prohibitevly spendy int time and dollars and you dont allways get what you expected. you may have unnessasarly runied a good piece.
look int bbl. mfg's that make bbls for your piece see if one is being made in the desired caliber for you model of weapon, if you just want cheap ammo to shoot get a 22.simi auto. and nock yourself out.its just as much fun. as a custom cal. gun. if you do change let me know how it turns out.
