Only one half to the story right now. I got this pistol with the understanding of the complicated background. When kimber first released this pistol in 2011 and there was alot of controversy due to the malfunctions showing up. This pistol was designed for deep concealment being a mere 3.9" tall, less than an inch wide and only 5.5" back to front and 17oz unloaded it was up for the task. Well I took this noisy cricket out to the range for some #pewpew time. Now @kimberamerica specifies that only premium hollow point ammo between grains 124 and 147 are to be used and most importantly what they recommend, which is @hornady_mfg tap among a few others. Well I went out with some critical duty, critical defense, HST 124 and the 150 designed for micro pistols among a slew of others. Nothing seemed to function for more than a mag. At this point all I had was the tight fitting 6 round mag that came with the pistol so reload times we a bit slow ;). The main issue I was experiencing were FTE. The slide would come back attempting to extract the spent casing and it would ride the top of the next round and hang up on the face of the next rounds brass. No form of tap, rack, bang would fix this and in fact the problem could only be fixed by an administrative reload. I tried every bit of solution I could think of but nothing was working. The only thing I can think of was it could possibly be due to a design, from what I could tell, to keep the pistols grip area as short as possible. That was a small bump under the slide meant to compress the next round in the mag. Problem is when the slide moves to the rear it allows that next one in the mag to move up causing an interference with the spent shell being extracted. This didn't happen every time I fired the gun but it did happen a few times for each mag and it was never consistent, meaning it wasn't always the first round on a topped of mag or the last. Well I contacted Kimber and they were more than happy to help. I received an RMA number quicker than I could clear a jam on the Solo (sorry guys but I had to). So right now the experts are taking a look at it to see if they can fix that beautiful piece of art.
