Got the 10mm Remington to the range today. What a blast. This is a serious gun. I brought 1 box of Sig factory 180gr ammo, and a variety of hand loads (chrono data below). Function with factory and JHP hand-loads was 100%. My "light" cast hand-loads had a tendency to not quite cycle. Seems they will need a bit more crimp and / or oomph (I failed to try the plunk test before shooting). I noted the gun as "tight" earlier. It definitely loosened up with some shooting.
The grips are intense. I cant decide if I like them or not. There is a high likelihood that I'll be trying out the gun with my rubber Hogue 1911 grips in coming weeks. Seems like it might be more comfortable. The recoil is stout, but not particularly uncomfortable. Cut on trigger finger didnt help me.
Brass gets launched a mile. Ok, seriously, maybe 25 feet behind and to the right of my right shoulder. This is a bit annoying for a cartridge that isnt common at the range - made picking up brass to reload a chore, as it was launched onto the gravel road behind me (after ricocheting off the metal roof).
Different loads seem to shoot to different point of aim, especially comparing the 140 cast loads with the 200 JHPs. The 140s were 6"+ high at 25 yards.
Trigger isnt bad, but I'll try to adjust and see what I can do to smooth out & lighten.
Would I buy it again? TBD. Its fun to shoot, hits with authority, and empties 2 liters in a hurry.
