"I have seen the same videos and grief about the Glock 42...there are a handful now in my area at the range and not one of them has ever missed a lick even with the ammunition touted to cause failures and caused all the skepticism about the reliability of the new Glock nobody wanted.
I'm not an R51 aficionado but I think those who are interested might wait until there are enough examples in the field to make a judgment as to whether or not it is a success or failure. It is way too soon to decide one way or the other."
I wouldn't say it's definitive, but as an "enlightened fanboy*" of the gun, I will say there is ample evidence to suggest there are
common if not
inherent/universal problems with the bolt camming and triggers (the rear sights, too, but that's a really stupid issue to crow about as loudly as people are)
From what I have gathered so far (which ain't much) the upward/downward camming of the bolt block by the slide can (often?) cause enough binding to make operating the slide or getting the action into battery difficult or impossible. Seems present on all guns, but in extremely widely varying and inconsistent amounts (suggests quality rather than a design issue). Other accounts suggest the disconnector may be contributing to the slide difficulties, which would jive with other accounts describing horrible trigger pulls in addition to slide troubles. So, we may have a combo of machining tolerance stackup or issues on the bolt block, and rough or out of spec FCG parts. Neither of those sounds out of line for a 400$ gun by Remington (sorry to say it, but these R51's were never going to be "nice" at that price point) with zero field experience or followup improvements.
That it's a new design makes its execution all the more difficult, and also seems to give lots of owners and e-net commenters ample excuse to throw up their hand and say "the gun's a POS" when it doesn't fulfill their every desire. I haven't read a single negative review where the writer/filmer even
attempted to diagnose where/why any binding or roughness was occurring. I hate to sound like an old man in my 20's, but so many people are pathetically lazy/inept when it comes to troubleshooting
anything for themselves, and see even a simple device like a pistol as an inscrutable black box.
I mentioned it on another thread, but the best review so far by a very wide margin is by a fellow of the name RyeOnHam on youtube, wherein he breaks down the R51 and Model 51 side by side, explains the difference and improvements, goes through the operation of the action, and appraises good and bad elements of the new design.
38min review; get some food and a beer
He ended up having to send his pistol back, but he says he is not disclosing why until Remington has an opportunity to satisfy him. Far cry from a sight-unseen "the gun sucks. pass" belch that echoes through the halls of GlockTalk. Whole lotta folks out there absolutely delighted they were "right" about the gun having issues, as if that accomplishes anything for anybody.
