Ever since purchasing my Spartan i have had a reoccurring problem with the slide not slamming all the way home. It leaves about an 1/8" gap, about twice every mag, not allowing the gun to fire. I figured the gun just needed some breaking in so i kept shooting it. Ive put about 500 rds through it so far and the problem persists. So today i field stripped it, cleaned it, oiled it and put it back together. I took it to the range and now about every other shot the hammer does not stay back. I took it apart again and everything looked in order, but then again I am far from a 1911 expert. Any help is much appreciated.
