Hey man looks good. I have noticed I could fit 18 in my magazine as well so I played with it at the range to see if I could get it to malfunction. So far so good, no malfunction but as a lot of other people might point out, we are overloading it and it is not meant to fit that many rounds. Might jam in a tricky situation if defense is why you keep a gun around. Also, don't store it with 18 rounds in it. It should be good to store with 17 though that way it's ready to cock, lock and rock.
Theres a video on here that "teaches" people to remove the baseplate using a pair of vice grips to hold it. I personally dont do that, im not a pussy i guess lmao
