Yeah, (this is all rhetorical because I'm sure you know better) how many companies make a 1911? In a particular frame depth, how many calibers are available in those 1911's? How many 1911 companies make their own mags? How many drops of lube does the 1911 owners manual tell you to use?
How many companies make a Glock? Who makes the best Glock mags? How many shoot 9mm out of their G21 or G30? If I was trying to shoot 147gr cast wadcutters in my G26, and was having problems after about a 100 round range session, should I send the gun back to Glock to get fixed or would the recommendation be that I may be better off using 124gr copper jacketed ball or hollow point ammo?
If your gun is working fine, you can use whatever lube you want, and any round you like, or any mag that fits in your gun.
If there is a problem, it may not be the gun. Do we ever have folks on the forum that have a new G17 and are using the cheapest 115gr training ammo, and in their first 100 rounds, have repeated cycling problems? Sure we do. It's like a quarterly event. Is the G17 broken? No, the problem is weak ammo that has a problem driving a new recoil spring assembly that is designed to handle NATO ammo and last probably 10,000 rounds before replacement. When new, that cheap ammo won't work in the gun. The gun isn't broken, it is bad ammo. Shoot better ammo and the gun will work, or 300 rounds later, that G17 probably shoots that cheap stuff just fine. The gun isn't broken.
