I have a new G-30S that I will be taking to the range Monday.
I have no doubts about it. This will be my second one.
The first one never missed a beat from the first round through the last one. Most of my range rounds have been WWB, or Commercial Reloads from a friend. After trying several different carry rounds, It has shot up what ever carry round that I have loaded in Light to Heavy, Even the Flying Ash Tray, or the ones that looked like a cheap drill bit, or RIPs.
The only thing is it won't fit in all the same Holsters that I have for My G-23, & G-19. Just a touch wide in the waste, but what the heck so am I.
I picked this one up slightly used, The couple that had it were both shooters, but all they had were 9mm, and the 45 ended up being more than she wanted, When he fired it, the Trigger guard hurt his middle finger. Because of this they were ready to let it go, after 100 rounds. They found a G-17L that they liked better.
It made a good day for all of us.
I had the same problem with my first one, and a file and sandpaper will take care of it. I also got four mags with it.
