Are you planning to shoot lead? If so, go aftermarket. My zev tech barrel runs just fine without issue. If not, the factory glock one works well also.
I shoot predominantly suppressed, and factory 147 gr works well. Wanna really be impressed, shoot 158 gr fiocchi
Is the 158 grain Fiocchi more quiet? Slower?
Any leads on one for a Beretta 92
Rethread the factory barrel there is more than enough material, have done a lot of them for people.
