After saving for quite some time I have purchased a new Glock 30 in .45 ACP (3rd Gen)! This is my first Glock and I love it. Fit and finish are excellent as well as balance. The only problem I've got is the 10th round is HELLACIOUSLY DIFFICULT TO PUT IN THE MAG, even putting the fully loaded mag in the Glock requires a shove. Currently I'm leaving the magazine loaded to stretch the spring out some. After replacing all the old oil and grease with what I prefer, shes smooth as silk . The only personalization that I plan on doing is a stainless steel guide rod spring and possibly Truglo sights. Since this is my first Glock, anything I should know?
