Had the new VP9 2020 at the range today, and went very badly. With the Trijicon SRO (shown in the pic) and my usual range bulk ammo of the Remington UMC 115 gr, I got multiple failures to fully cycle. A few stove pipes, and a few failure to pick up next round but did successfully eject. Looks like a new spring / weak ammo bad combo. Forgot to bring my +P ammo, so didn’t get to try that. Hoping it’s just a new spring issue. Same ammo in my well used VP9T, with the same optic (but mounted on the trijicon rear sight adapter) worked perfectly last week. So I don’t think it’s the weight of the optic + the weak 115 Remington UMC. Next time, will also bring the VP9T (so I can grab the spring from that to test) and also +P. But today, I couldn’t get through an entire mag w/o some failure.
EDIT: went back out to range, this time with Federal 115gr ammo, and got through two boxes without any failures or problems of any kind. Ran the 17 round mags, filled to 17. VP9 2020 real nice gun.
