no issues here
Ive go a gen 4 27 and so far it is flawless. Look forward to seeing what the problem is. Looks like either a spring problem or maybe slightly out of spec frame. I guess anything can have an occasional issue. While the Glocks are obviously cheap to build they seem to have done something better than other poly mfgs. I shoot with guys who have M&P's, XDs, and Taurus and none of them are as forgiving or reliable as the Glock. My old S&W 3913 and my Colt series 80 officers ACP both beautiful and more expensive to build but dont shoot any better. I stopped carrying the 1911s after 3 different ones would not reliably feed hollow points 100%. the 3913 is super reliable and the best IWB carry gun I ever had.
