Has anyone had problems with their stock glock mag springs? They work good at first, but seem to start getting weak within six months or so. I ended up changing my glock 22 and 19 mag springs to wolff springs because my last round just didn't want to load into the chamber. I tried to do the same with my 30 but the results weren't as good (see other thread). So has anyone else had problems with their glock mag springs besides me? Do your springs last years and years? Let me know. I am just frustrated because my sig mag spring is just as strong now as the day I bought it (1 year). Just for your info I do keep my guns loaded, always!!!
