It is a P365 slide that I had milled to accept an RMSc footprint red dot. It was milled by NCENGRAVERS. The frame is a Macro 17 round frame that was trimmed down to line up with the 365 (3.1") slide. I put a few hundred through it. I bought the slide used, so unsure of round count. I did replace the extractor and spring just in case. It will come with one 17 round mag. This is a build, so I do not have a box, or paperwork with it. I do not have a rear sight plate for it, as I had it milled.
