do the Gen4 Glocks still utilize a polygonal rifling? I think I've read somewhere that they have changed to a more conventional rifling lately, but I couldn't find any actual confirmation...
Im very suspicious about the origin of Gen 5 barrels, there was no reason to change it and the finish starts wearing after the first box of ammo? they seem to be using a sub standard finish, the Gen 3 / Gen 4 takes 1000's of rds to wear the finish on the barrels
y'all talking about Gen5 now - I'm still not clear about whether Gen4 has polygonal or conventional rifling...
There are 2 reasons I can think of. As listed in the video in post #7, the FBI wanted lands and grooves so bullets could be more easily linked to a firearms. The other reason is probably use with lead bullets or possibly some of the new polymer coated ones. Polygonal rifling can have problems biting on lead bullets. I remember reading an article where a police agency had bullets tumbling at 7yds and out trying to shoot lead bullets during training.Im very suspicious about the origin of Gen 5 barrels, there was no reason to change it and the finish starts wearing after the first box of ammo? they seem to be using a sub standard finish, the Gen 3 / Gen 4 takes 1000's of rds to wear the finish on the barrels
I think they contracted with a outside source possibly US to make the Gen 5 barrels to save on costs
