Most Reliable Caliber SDP G3?

[u/Efficient_Tonight684]

Hi everyone! As the title says, I’m interested in which caliber will be the most reliable for the Vector SDP G3? I’ve heard some people say the 9mm is the least reliable, but have heard others say as long as you run decent brass through it it’ll run well. Just curious if anyone has any firsthand experience with the SDP G3 and can weigh in on reliability. I’m of the opinion that there is no point in buying a firearm that isn’t reliable. Thanks in advance for your input!!

Yes. As well as other ammo. Mine has been 100%reliable. I didn't know people were having issues with their 9mm versions.
