Yeah I've poured money into it. I had the EOTech on it, but then I found that Leupold CQ/T for a steal and couldn't pass it up. From there I tossed on a couple of MagPul toys, I have my FDE Miad grip, but didn't have access to tools while I was back on leave, I also plan on getting A EMOD in FDE as well.
A Glock 27 would be nice. I like the fact that the larger magazines will fit into smaller Glocks of the same caliber (17>19>26, 22>23>27).
I really, really like that Glock 30, by the way. In the past, I've carried a Glock 19, Colt Agent .38, and Colt Officers .45 ACP, and this is by far the best. I'd recommend one of them to anyone interested who's wanting to buy a pistol for concealed carry.
And for a full-sized pistol for open carry, I am very happy with the Glock 22 (I also had one issued to me when i was a parole officer). True, pistols like the Wilson Combat CQB or the H&K USP might have nicer ergonomics and smoother machining, and while I'd certainly love to have either, cannot justify the expense when the Glock can be had for half the cost of the HK and a fraction of the cost of a suped-up custom 1911A1.
