KKM Match Grade Barrel For G41
$185.00
These are at least as accurate as anything else out there, and you can shoot lead with them. They have better chamber support, while still having a bit of extra space in the chamber like the factory barrel so that they feed just as reliably. The glock factory barrel is several thousandths oversized, which while reliable causes the infamous glock bulge in the fired cases. The kkm seems to be slightly oversized but tight enough to contain the bulge. I still use my GRX pass-thru die but it is not really needed with this chamber most of the time with standard loads. Best drop in on the market, period.
