The bullets sized to .356 are probably lead bullets which are not recommended for your glock.

.356 lead.... .355 usually plated or metal jacketed for 9mm. Want to find out what size lead works best then slug your barrel.

I use Rainier plated .356" 130 grain RN bullets for most of my 9mm shooting. Great bullet. I've shot a couple thousand through my 17L, 19 and .38 Super. They even shoot well in my model 10 .38 Special.

I think the differences we're observing are due to rounding a more-precise number. I believe about all 9mm or "0.355"" or "0.356"" bullets are actually 0.3555 inches in diameter. (Lead bullets usually are slightly larger.)

For plated or lead, 0.356" works better for me. Jacketed seem to do fine @ 0.355"+/-.

355, 356, whatever it takes.
