I recently purchased a pt111 as my first semi-auto. I absolutely love the feel, weight, trigger and look of this gun! I took it out for a break in after cleaning it and with 200 rounds of Winchester 115gr target ammo and the gun handled perfectly. I was hitting low and left but very tightly grouped. Took it out several other times since that break in without a hitch. I took my daughter with me this last time and the gun would fail to feed and the slide would not lock after firing the last round with her shooting. I chalked that up to her grip strength. However today I took the gun out and had multiple fail to feed problems with the same Winchester ammo. I have cleaned the gun after every outing. Any recommendations?
