I've been considering a G27 or G33 and then picking up an aftermarket barrel for other caliber to haveboth but I read a lot about the lack of support for the Glock in 40sw and I was wondering if this is true for the 357sig as well?? Is the Glock 33 more supported than the G27?? f I know that the 357sig barrel has plenty of support, I will get that one first and then pick up the 40 aftermarket barrel The other way if I get the G27, then I would want to pick up both barrels? Do these aftermarket barrels reduce reliability?? (these are not conversion barrels) Thoughts?
