Glock 17--115gr or 147gr bullet weights??

I've shot sort of a lot, and I can't really say I see that much difference.
I've never really set out to do a pepsi challenge, though.
Just remember, factory loads don't necessarily obey the whole "heavier bullet = less felt recoil" paradigm that everybody seems to be on board with.
I had some WWB 147s that were total snappers. Power factor of 150! Unreal!

"heavier bullet = less felt recoil" is only half the paradigm. "heavier bullet combined with fastest powder = less felt recoil"
Given the flame I've seen come out of barrels when WWB ammo is fired, I'm guessing Winchester uses a pretty slow burning powder in their white box loads.
All seem the same to me, and all have fed fine. Winclean 115, 124, and 147, as well as Ranger RA9T's 147gr. You should pick up a a 500rd case of the RA9T's from Wolverine if they have any left. Excellent price. They have worked flawlessly in mine. 
last summer I did some group comparisons with montana gold 124's and 147's out of my CZ and my glock, using various powders but all loads in the 128-130 PF range. Except with a titegroup load, the glock consistently shot smaller groups with the 124's and the CZ grouped better with the 147's. With titegroup the glock performed as well as the CZ. That being said, I'm not sure I would care to extrapolate the results to other manufacturers bullets or factory ammo of any kind.
I have used mostly Remington UMC 115 grain "Metal Case" with mine. I have found this to be a good all-round cartridge. I've tried every 9mm cartridge I can find (including some really lame ones like Fiocchi and -the grand champion of inaccuracy - Fiocchi hollow-points ) and I keep going back to the 250 and 500 round boxes of Remington 115 grain.
Some of the European-made 9mms I own seem to be a bit more picky with their ammo and don't get the same results with a 147 grain bullet that they do with 115's or 124's, but the Glock 17 is not like this. The main store I shop at (Reliable Gun & Tackle) had some Speer "Lawman" 9mm 147 grain. These were not a hollow-point - just a flat nose 147 grain with a copper jacket. My other guns didn't seem to agree with these bullets, but they worked great with a Glock. For awhile I was thinking that my accuracy was better with these, but I'm not really sure of that now. I'd need to bench it and do some testing to really figure it out - and I'm not really that interested in these small differences with a gun like the Glock. The Glocks are duty pistol accurate (the best I can generally do is to keep 9 of 10 shots inside a 5 inch circle at 15 metres (50 ft.). If you are doing any better than that, then I'd say you are well above average with your Glock) and are awesome in their reliability, but they won't hit the same spot all the time no matter what you do. I'm using a totally stock gun. With a 3.5 pound connector and a really tight Bar-Sto type barrel you might be able to shrink your groups down a fair bit.
In my view, Glock seems to be about the same with all the factory ammo. There is nothing that it really doesn't like - other than maybe Fiocchi hollowpoints - Remington hollowpoints work great though Like to pick those up for our range's annual pumpkin shoot!
