'trouble for awhile causing the rounds to nosedive but even that problem
Seems to have amazingly cleared it's self (that mag is marked and a close watch will be made).
The pistol is finished very well in some mysterious black coating that so far is ,fairly wear resistant, however I am not carrying it on a daily basis. There are öono milling marks and it melts into your hand but when firing failure to maintain a good grip on the pistol will allow the grip safety to keep the pistol from firing. A good hold makes this a non issue.
I found my pistol does not like steel cases, I purchased some Winchester Steel by mistake and used it in the first couple of magazines shot through the pistol. Those rounds also produced the only malfunctions encountered. I did fire the remainder in two of my FN High Powers without any problems.
Disassembly is only a slightly difficult with my arthritic hands however reassembly is very difficult and the instruction book has poor photos with the instructions. I finally found a non marring tool to use rather than fingers and nails, also I found some profane words directed at Remington helped only slightly in reassembly but considerably comforted my ego. After a dozen or so times at reassembly I can accomplish the task with fewer cuss words.
I like the little 9 mm as it points nicely and has light recoil but does shoot several inches low. Remington needs to offer various front sight heights to cure the problem. Despite the detractors on these forums, people who probably have not purchased an R 51 nor possibly even fired one, I like the pistol. I bought mine for plinking and informal target shooting as I have CC pistols already but I am sure that is what Remington hopes will happen.
