They should work fine. .001" oversized isn't going to hurt anything and you might get excellent accuracy out of them...tight bore fit and lots of bearing surface. I wouldn't try max loads with them, but if you push them around 1,000fps they'd be pretty much like typical 147gr JHP defense loads. A little slower (say 900fps) and they're a perfect Minor load. R,
What about in a Glock 34 with factory barrel? Or, do I need a after market barrel like storm lake
