The quality of your Glocks may have been excellent but not the case here, have problem with leading with the polys.
Not really much experience with glocks though, had to slow down a lot getting older. Used to run 50k thru them a year during competitive years. Had one of the first 40s out, won several state IPSC champions in A class. Down to 12-15k now.
only kept a couple 21,19,34,35,37,38,17,23, 17L.
by your comments I would guess your in the 100k group
