Range day.....
I fired about 100 rounds of factory made Winchester 124gr FMJ in my new S&W Shield
no thumb safety.
The sub compact shot great & feeled solid in my hands(both right & left).
The new 9x19mm cycled & fed all the Winchester brand FMJs. The only
2 minor problems I had with the M&P Shield was that it did
not really fire and cycle w/o a seated stainless magazine,
.
The Shield also seemed to choke a bit when I wanted to work the slide or load 124gr FMJs using my hands rather than the slide release.
I think the smaller size slide or maybe my method was to blame, not the Shield 9x19mm.
I've seen Youtube clips of Shield shooters who load, rack, switch mags, etc without any misfires or jams,
.
I guess I need another 200/300 9mm FMJs to run thru it.
Overall, Id give the M&P Shield high marks(B+/B-) but it seems to be suited for a right handed gunner or CCW holder.
I'll hold on to the 9mm Shield for now but it will take some more rounds before Im 100% sure I like it.
