The more I dig into this SACS Nina, the more I realize they did not fit many of the parts.
The slide stop had me baffled but I think I finally figured it out and came up with a temporary solution.
The slide stop pin is .196". The slide stop pin frame holes are .198"+. My new EGW .200" slide stop pin will not slide in.
I just discovered odd gouging in the tombstone cut out and metal swagged outward. A pieced of metal broke off that gouged area.
My slide stop was originally not engaging the slide notch all the way up. It was catching the very edge which also pushed the corner of the slide outward building up an edge.
My diagnosis, the sloppy fit of the slide stop pin to the slide stop pin hole in the frame caused the slide stop to not fit flush to the frame. Look at the paint wear forward of the slide stop pin hole on the frame.
The slide stop inner lug was tight up against the inside frame rail which caused a drag.
I still dont know what caused that gouge in the tombstone cut out but last week when I started messing with it, I saw a buildup of something on the bottom of the slide stop lug (same area as the tombstone cutout gouge) and 60+ year old eyes and not wearing my 3.5+ assistance, I hit it with a pointed pick, and it went flying off. I could not tell you what it was, nor could I find it.
I filed and stoned the inner lug of the slide stop to be closed to flush with the slide rail to minimize drag with the slide stop (to aid in empty mag lock back)
dry testing all my 9 round Springer mags was a success.
After shooting season, I will send my gun off for the .200 EGW slide stop to be fitted. I dont have the tools to do that job.
Besides the slide stop issues, I shot this gun in a match this past weekend. I was that close to getting a 500 (perfect score). Accuracy with this shooter will do its part if I do mine. It was very hot (I could feel the effects of the heat), my vision was hindered by sunlight glare and when I walked up to the target after 25 rounds.... I saw this.
There were a few times I moved but hey, those movements were into the 10 ring.
