Well, after all the hate and discontent that the Remington R1 has caused me, I finally called Remington and told them about the extractor issue and other problems.
The reason I was reluctant to send it to them (under warranty) is that I sent it to them when I first got the pistol to correct the front sight problem. They sent it to some "gunsmith" who did not do anything to correct the problem. I was very specific about the problem, and he said he fired it. BULL.
Anyway, when I called Remington this time, and described the problem about the extractor issues, they want it back there. So they are sending a Fed X package to send it to them, at their cost.
That was a surprise.
Also, when I asked about who would do any repairs, they said that the previous "gunsmith" was no longer used, and it was in house now. They had several complaints about him.
So here is hoping they correct the issue. If not, it is gone.
I have the Glock model 40, mos, and after all the modifications were done, it shoots extremely well, and is far more accurate than the R1. I have a gen 4 model 35, mos, 40SW, with the Leupold Delta point Pro sight (2.5 dot), and it shoots so VERY well, that when I thought about the 10mm, I started looking for the model 40 mos. I could not find one at that time, so there was the Remington R1. I then ordered the Model 40 mos, and after all the mods, (edge trigger, kkm comp barrel, like all the Glocks that I have, now 3) I have another great shooting pistol. I wish I could say the say thing about the R1. It may still happen, but at this point I am not optimistic.
I have found that a Hornady 180 grain either XTP or HAP with 13.2 grains of AA9 gives 1276 fps chronographed out of a 6 inch barrel, avg of 15 rounds, twice, from the Glock, with no pressure signs with the Starline brass. I really like shooting the 10mm with the Glock, and recoil is no problem, mainly because of the weight of the pistol, and the Comp helps with the whip.
