Just got back from quick range test with my RXM running it dry as new right out of the box. Trigger gauge turns in 5-1/2 lbs consistently here after having run about 50-60 rounds through it at the range.
On a scale of 1-5 on my first session, it scores a 3-1/2 maybe 4 due to some issues I ran into.
My ammo was 124 gr fmj reloads from once fired brass in front of 5 grains Unique. The reloader was a professional reloader and I have shot hundreds of rounds of this same batch with no FTF except for a couple light primer strikes by a different gun I no longer own.
This RXM had 2 FTF in the first 15 rounds and they were not from light primer strikes, but failure to cock/set the striker. I have never experienced that before as the trigger appeared dead when squeezed and yet there was a live round loaded in the chamber from the previous round firing, ejecting, and loading this next round. I checked the extracted round and found zero evidence of a primer strike. I didn't take a lot of time diagnosing the condition except to view the slide was completely in battery, so there was no out of battery condition that I could detect.
2 in the first 15 is not a good number IMO. I experienced it again in about the 8th or 9th batch tested during a rapid fire session. I only loaded and shoot 5 at a time when testing functionality.
The second issue is that the rear sight is causing me to shoot left and the groups appear I was shooting a shotgun with 00 buck at both 7 and 10 yards. I brought along my Canik and my SAR K2 45 and shot both to compare groups. The Canik and K2 45 both shoot much nicer groups and center, so I am rather convinced it is not me, but the Ruger rear sight that need adjusting.
I did not mount my optics yet, but will once I adjust the rear sight with my sight pusher. Not much good in trying to co-witness when the factory set sights are off.
The photo is of 2 5 round defensive rapid fire sessions, one with Speer 124Gr +P Gold Dots, and the other 5 rounds with my 124 FMJ reloads. Point of aim was the red circle of which the holes are from prior shots from the other side of the folder paper. The yellow circle is from the rapid fire sessions which if you count was only 9 round through. One round never got through as it was another FTF which occurred, so that makes 3 FTFs in the first 50 rounds tested.
Next time I go out, I'll lube and bag this gun and see what kind of groups it gets with factory new Winchester ammo. The rear sight will get moved before then as well. At this time, I will not carry this gun as a SD gun because of the FTFs experienced on the first run. The gun was not out of battery either as I checked it for that. It simply failed to set the striker.
