thanks for posting the pics, e.c.
i shot 150 rounds through the spartan on the day i got it. 50rnds factory armscor fmj's and 100 rnds reloaded fmj's.
not a single failure. not fte's, no ftrb's, no premature slidelocks, no failure to slidelock on an empty mag. no nothing. it worked flawlessly.
the slide-to-frame fit is excellent. the barrel-to-slide fitting is excellent. so is the barrel-to-bushing-to-slide fit.
the gun is factory zeroed and shot to point of aim. it gave me 1hole-1in 5shot groups at 5 and 7 meters offhand. maybe i will lighten the trigger down to 2.5#. but maybe i wont. not sure yet.
the msh is a tad too long and does not fit flush. but it don't bother me much.
the one thing i would change out is the barrel link. while it does not negatively affect the accuracy or function of the spartan, it's ugly.
this is a very nice gun.
