Welcome! I'm sure there are a lot of lurkers who hear about the long delivery wait and wonder if the wait is worth it, especially with the messages from folks who have feeding or other issues. My experience puts the R9 in the same class of fine engineering and design as my Gold Cup .45 and my Seecamps. All tools have limitations, but these have have unexceeded beauty, reliability, fit and function for their purpose. I'm hoping the R Brothers next effort is a six+ round .45 platform: I'll order mine the moment they start taking orders!
For what it's worth, I had similar feeding issues when I started; if I racked the slide manually, the next round would usually nose into the feed ramp and jam, and I had one or two similar jams when shooting the first 50 or so rounds. After that the jamming problem disappeared and rounds feed perfectly but I still take the precaution of smacking the back (primer side) of the magazine against my palm after loading so that the angle of the top rounds are aligned as well as they can be.
BTW... I waited a year for mine (custom SN#) and it was worth it!
