Today marks two weeks since I found and bought my R51 (SN 6xxx). As I mentioned in my introductory post, the slide was extremely difficult to work. Now, it has loosened up considerably but not to the point as shown on early SHOT videos.

I took it to the local range yesterday and shot it about 120 times. The first 100 were with Federal FMJ. I only had one hiccup, that on the very first string. The fired round failed to eject causing the next round to fail to load and simply lie, stripped from the mag, and loose.

BTW, I estimate that I have shot it about 500 times now.

From then on, the pistol worked perfectly. I loaded 7+1 in order to test it under carry conditions. When I switched to Winchester FMJ I experienced one more failure similar to the one above. I shot another couple of 7+1 mags and called it a day.

There were some minor problems however. The first was a wandering rear sight. Recoil made the rear sight move about 1/4" or so to the left. I could move it back to center using both thumbs where it would click into place. It seemed to move after about three magazines worth of shooting.

I have not decided how to solve the problem. I could send the pistol back. Or, I could have someone just fix the sight in place. Really, I don't see much use for adjustable sights in a carry pistol. (I did not notice any movement of the front sight.) Lastly, I could just keep popping it back into place. I'd appreciate advice.

When the sights were in their proper place the bullets went where aimed, btw. (See attached best target @ 21'. Target is 6.75" in diameter)

Another problem was the second magazine. Try as I might, I could not load the seventh round into it. I had read elsewhere where another user had the same problem. So, when I got home and cleaned the pistol I loaded the magazine with 6 rounds, hoping that the spring might give enough in a week or so, enough that I could load the seventh round. We'll see.

I'll probably take it out to the range a couple more times before I carry it concealed. It hides more easily than the J Frame does, but I know the J frame will shoot five times no matter what.

Finally, I have yet to shoot it with Remington ammo. I found some of the Remington new hollowpoints at Academy but bought Hornadys instead because they were cheaper. I'd like to find some Remington FMJ and see if pistol shoots those more reliably.

You could use a center punch to stipple the underside of either the rear sight or the dove tail on the slide. Just two or three times should be enough to offset the metal enough to keep it from drifting on its own.

Ok! I'll give that solution a try. Thanks

You COULD stake the slide to create a retention dimple in several choice places on the slide. I personally would try an anaerobic adhesive like Loctite Purple (#222) on one end of the sight pad at the dovetail's floor.

MAKE SURE THE LOCTITE FORMULA IS LOW STRENGTH & REMOVABLE.

If it is really loose, then use Loctite Blue (#242). You only want a little of this formula between the dovetail floor and the bottom surface of the sight if you have hopes of adjusting the sight by conventional means. Just a touch on one end. Move the sight over in either direction, apply a small smear on the surface that the sight will cover when you drift it back to its "pre-marked" position. Note: Pre-mark after satisfactory sighting and before starting this process.

DO NOT USE LOCTITE RED (HIGH STRENGTH) OR STUD-N-BEARING MOUNT OR YOU'LL HAVE A PERMANENT "FIXED" SIGHT.

Good advice...

Sounds like a good way to start. My rear sight is not very loose. So the low strength loctite might just do the trick. Thanks
