I put about 250 rounds through my Spartan today.
Once I got the rear adjustable sight dialed in, I could make upper A/B (head) shots offhand consistantly at 25.
No failures of any kind. Ammo was 230 grain, FMJ Win White Box.
This one's a keeper.
The only things I plan to do are:
* open up the rear sight,
* use a lighter recoil spring, and
* add some type of small mag well (the hole looks small after shooting double stacks for so long).
I forgot how much .45 ammo costs and the amount of recoil with stock springs. I picked up my brass and need some .45 dies now
