This was the factory G34 barrel at 15 yards.

I also use titegroup with 147gr. 3.5gr seems to work best for me out of my m&p9c. I am pretty new to reloading and have not tried any other powders. But do like the cci primers over Remington. What primers were u using?

CCI almost exclusively (because I bought a lot of like 30k a few years ago). I have thrown in Winchester every now and then.

Jonny, does the slide lock open when you empty the magazine with this load? Thanks.

I believe so. I'll have to double check and I'll let you know.

Thanks. I tested 147g blue bullet over 3.3g TG and slide did not lock open.

I tested the G19 and the G34 with factory mags and Magpul. All locked back.
