The newbie here who just came back from the range with my wife. We were shooting rami bd 2075 for the first time. 50 rounds each. I bought it new a month ago (2019 edition). I didn't clean it, as I was not aware until now that I need to clean a brand new pistol. Anyhow, most likely the problems we've have experienced are not the same as OP; however, there was some discomfort firing this Rami for sure. I should mention that the last time I had some range experience was 25 years ago in the army (ar16 & uzi) and my wife never fired guns before (besides disassembly/assembling ak47 in high school).
What I like is how it fires. Feels smooth.
What I didn't like and I understand that I lack experience are the following:
a) During reload of the magazine, it really takes some power to slide back and at the same time pull the lever on the left side up. We really struggled w/this. I can't find a good youtube video that shows this moment step by step. I think we might need to take a private lesson on how to use this gun.
b) Twice it was not ejecting (i.e. pulling trigger & nothing happens, take the mag out, try to slide back and it doesn't slide). Asked shooting range watch guy and he struggled with it too but managed to slide it back eventually. At that point, I really thought maybe I need to call for warranty :-)
c) loading 14 mag was no problem, but loading 10 mag... i could only get 8 bullets fast. the last two was/is a real struggle. can't imagine putting so much effort to load 10 mag when/if time comes.
Also, if someone can point me to good youtube video instruction on how to clean this specific gun that would be great.
