"I titled my review "Raw Fish" for a reason - out of the box R51 is exactly that. Number of issues experienced by owners at this point is well documented, and those who did their research most likely refrained from buying it. I totally understand - some of us like fish well coocked, however many do like sushi. I happend to belong to latter. With that said, my date of R51 purchase was 3/22/14. I got one of the first two guns received by my BP. I'm no exception - number of problems I experienced is inline, or even higher than highlighted in most reviews. And yet.........as of date of this review, I have 713 rounds through the gun, and it is smooth as silk and performs flawlessly. You ask: "what is the secret?" Answer is simple - I "cooked my fish." Or in another words - I spent more than dozen hours working on this gun, and addressing issues one after another. Some of them were simple, i.e. ability to push rear sight from side to side with not much force - blue locktite, front sigth shifting to the right during shooting - blue locktite. Some were more complicated - magazine insertion problem - modification to the frame, feeding / stove piping - another modification to the frame and polishing of various parts of barrel, slide getting stuck and cycling issue - more polishing of various parts, difficulties with manual cycling/taking of battery - modification to the slide and bolt polishing, gun going on battery while magazine is not empty - another modification, trigger wobbling side to side - modification to trigger group.... As you can see, I had my share. But it is mostly over (I'm still considering changes to trigger group, but decided to wait - hope there will be aftermarket replacement for trigger/pin/springs available), and now gun shoots all ammo, as opposed to only Remington's +P prescribed by manual, it is smooth and accurate at max BP's range distance, which is 25 yards. So, if you want to have a short barreled semiauto gun with fixed barrel for $400.00 and change, and able to resolve issues that you definitely will have - R51 is for you. Otherwise your choices for fixed barrel single stack guns in same category are Walther P5 (~$1,100.00), H&K P7/P7M8 (~$1,500.00+) and Walther P5C (for unbeknown to me reason price for this one skyrocketed in last six month, and now commonly goes over $3,000.00). R51 is only one that currently in production."
