So I have been doing research during my deployment to decide what my next handgun purchase is going to be, and I have narrowed it down to the XDM 3.8 45ACP and the Glock 30. I was looking on Glock's website and noticed that they have not yet release a Gen 4 Glock 30. I'm a left handed shooter so being able to switch the mag release to the other side is definatly a plus. Has anyone seen or heard any possibility of Glock making the 30 in Gen 4? Also with the SF model can you use the normal 30/21 mags or can you only use the SF mags? Thanks in advance for the responses.
