Anyone knows if this mag extension for the G27 is a +1 or +2? I bought it off of LWD's site and it says +2 there in their description, but Top Gun Supply shows that it is a +1 (both look similar on their site). Since the factory mag can hold 9, I can load 10 rounds of .40 in there without needing help from a mag loader. However, if I want to load the 11th round, there is no way I can load it with my bare hands. I have to load it with a mag loader and it just feels like I am giving ALOT of effort to push it in. That makes me really wonder if it should hold 10 or 11. Anyone has this and can shed some light? Thanks.
