I plan on using a 125gr projectile so interested in loads with that (or close to that weight) but may try others. LMK what works for you and what you are shooting it out of and if you have it the PF.
 
125gr zero or toro HP over lots of autocomp, at 1.150" so it will feed in Glock mags. Chrono'd at 1350 on my piece of crap chronograph...until I shot it by accident, so 168PF.
 
124 RN BDX 1.155

Either 7.1 silhouette. Or 8.8 3N38

CCI small pistol primer. Prefer small pistol magnum when I can get them. Mixed brass

I just tested My wife's Czechmate load yesterday and I'm loading 124 Campro with 7.4gn HS-6, 1.150 OAL, PF 168

Same load here. Peak pressure according to GRT is about 42k -- if you have your barrel throated, you can load a bit longer, fit 8 gns of HS-6 and peak pressure goes down to 36k but still keeping a PF of 168-170, with more gas to work the comp.
 
3N38 with a Campro 121. 3N38 is probably the safest powder. Even if you were to completely fill the case, the gun still likely wouldn't blow up. Some builders will only warranty their open guns if you use 3N38.
 
I did the extensive research when picking a load for an expensive 2011 open with online pressure data..
Safest load to score major pf with 9mm major is
124gr (I like bdx) 1.175 oal 7.4gr 168-170pf 3n37 very light crimp
It’s not as flat as higher pressure loads but makes pf and won’t blow up your kids collage fund.
 
I have a power factor question. I'm going to shoot my very first match at the end of the month and today I went to the range with a chronograph and the 3 brands of ammo plus my regular 9mm reloads to confirm they'll all be good to shoot with. Now that I've shot 10 rounds (20 of the reloads) of each brand, it seems most of them don't hit the minimum 125 power factor that is required of all divisions. Is it normal for factory loadings to not make PF in a standard Glock 9mm? I should have enough of the Blazer 124gr that hit PF today to shoot my match, but I won't have much spare for reshoots or whatnot. I've attached a photo of my velocities and calculated PF

(I'm just a beginner, so if I'm missing something feel free to inform me. I'm not aiming for major, just bare minimum)

Most but not all factory ammo will make minor. However, some of those appear to be commercial reloads which are more of an unknown. Are you sure the chronograph you were using was set up correctly?
