Well after almost a year since this thread was posted, I've decided to replace the stock safety switch with an NDZ Aluminum Safety Switch, both for ease of operation as well as a sort of "just incase" to insure lasting durability.
It only cost me $17, so it's not like I broke the bank buying it, and if it works as smoothly as the reviews I've read about it suggest, then it will be well worth it. The stock safety switch is still stiff to this very day, stiff enough that I worry that it could possibly be a hindrance in a home invasion scenario, so a smoother safety switch with a bit more leverage. (The design of the NDZ Safety Switch looks identical to the one offered by Promag.)
