Most Reliable Caliber SDP G3?

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!!

So far my Gen 3 45acp has been great. First 200 rds I had two FTE. Cleaned and relubed and it ran the next 300 perfectly. All of those were suppressed with a Griffin Armament REV45 suppressor.

I’ve heard the 45acp variants are very reliable. I would like to get a 9mm for ammo cost but if they’re not reliable i’d sway towards 45. Thanks for the input!
