So my Glock 19 Gen 4 semi-failed on 2nd trip to the range. The slide lock lever fell out and gun malfunctioned. I dd some research and it looks like a known issue. Research says Glock replaced the slide lock spring with a new model that has more tension so i ordered one instead of paying $60 to send gun back to glock. Anyone else have this issue? Gun is only 6 months old.
