I can't speak for P226's, but my old FEG PJK, I barely noticed a difference. There was very little difference in recoil and point of impact. *shrugs* accuracy varied based on ammo manufacturers. I had a preference of shooting 115 grain.
I don't reload, so I just buy factory ammunition. When I first got my 226, I bought about 10 boxes of random ammo and weights. I wanted to make sure it fed that ammo properly before I went and ordered 500+ rounds of it.
Here's all I shot:
FMJ: Remington UMC 115gr, Winchester white box (forgot weight), Magtech 124gr, Winchester 147gr training ammo, PMC Brass 124gr and CCI Blazer Brass 115gr.
cost per round is the determining factor for me, the 226 likes all weights so does the 229.
federal, speer lawman, magtec are just a few of their favorites.
mostly 115 grain as it's a good practice weight.
i buy in bulk online (local purchased in the state of confusion; aka California) is a pain and i'm on a budget.
While I don't have a 226 (yet) I've shot all 3 weights pretty extensively in 6 different 9MMs I own and don't see a lot of difference except in the cost of bullets (I reload everything I shoot except defense ammo).
So, to help hold costs down I generally shoot 115 Grainers for practice ammo.
I don't own a 226 but every 9mm I've had, or still have (224, 250C, 290RS) all shot 115g, 124g & 147g more or less the same. I usually shoot 115g FMJ at the range & carry either 124g or 147g, depending on what I can find locally. I prefer 147g, but it goes like hot cakes when it's around. I've been carrying 124g lately & it cycles great & is accurate in my carry weapons
Depends on your needs to what bullet weight is best . Accuracy wise theres not much difference . More difference in brand and the ammo line than weight . For defense 124gr +P gold dot , aka " bonded "running along at 1200fps from a 4" barrel. Underwood ammo for defense.
For match use 135gr RN from Bayou Bullet running at 850 to 875fps for minor using tight group .
I no longer run and gun so practice is now a missouri 125gr swc at lower 1100 fps .
My 226 X5 loves 124gn round nose lead projectiles with 3.3gn of AP50 (ADI manufactured in Australia). Haven't got my manual handy to see what a similar powder would be. I use a Dillon 1050 except the Mr Bullet feeder. Do that bit by hand, just as a safety measure (on top of the double charge or no charge alarm).
I have to say that the X5 is the most accurate out of the box handgun I've ever owned. I was a bit of a fan boy of the H&K Elite in 9mm, but, I'm a Sig person now.
We get stung on prices, so, selling my H&K USP and starting to put $$$ aside for a X6 Match, once they are allowed into Australia.
I'm only target shooting. Using a handgun for personal defense is not allowed in Australia.
