Got my R51 a couple of months ago. Here's an e-mail I sent to Remington:
"I just bought a R51. I am not particularly happy with it's initial performance. I did disassemble, clean, and relube before first use. Couldn't get thru a magazine without multiple FTF or FTE. Used new Agular 124gr ammo. Out of 50 rounds, I only got one magazine string without any problems. After first session I cleaned it well with a spray cleaner and then sprayed it well with CLP and let it sit over night. After wiping it down and reassembling, it seemed to run better, but was still having 2 or 3 FTE and some FTF per magazine. Looked to the internet for solutions. The R51 Pistol Forum had some good info (thanks lklawson and Texas-Mark!). I took my dremel and polished the magazine feed lips and the barrel feed ramp. The barrel also had some burrs at the beginning of the chamber which I smoothed out. The last 2, 7-round magazine loads I shot all ran thru perfectly. I hope it keeps shooting well because I love this little pistol! It's weight, feel and accuracy are all what I was hoping for. Initial reliability needs to be worked on. I think you guys need to do better finishing of critical parts to solve those problems.
Anyway, I notice you guys don't offer R51 magazines on your website. How does one go about getting additional mags? The ones I see on eBay all look to be Gen 1, which I don't want."
I've gotten no response from Remington. Have found a Gen 2 magazine on eBay.
After another 200 rounds downrange I only had 1 FTE and 1 FTF. I felt confident enough to use it for my CHP class live-fire. 30 rounds at 7, 5, and 3 yards produced essentially 1 ragged hole.
Which ebay seller sold you the Gen 2 mags? Were they new in the box or loose?
All the mags I see right now appear to be Gen 1.
I'd call Remington instead of email.
I've called customer service twice (not pistol performance issues) and got through right away, got directed immediately to the right call staff, and got the answers I needed.
eBay store "Dan's Gun Room", seller "bettya5238". Magazine was new in an OEM blister pack. Thanks for the call advise. Guess I get in an e-mail rut.
Midway has gen2 mags for a not-outrageous price. Got a handfull earlier this week.
