Picked up a used Pm9 the other day in mint condition and really like it. I put on a Pearce Ext on one of the mags. Lakeline has a +1 Ext made of Aluminum that doesn't cover the entire bottom of the mag. They also make a polymer +1 that requires you to also buy a plastic base plate and it covers the whole bottom of the mag well. Has anybody tried either of these? I don't want the Ext 7 round mag because it just plain looks ugly. The Pearce looks a little better but for me I wish it would cover the whole bottom. Also does anyone make a plug for the bottom like you can get for Glocks. Thanks
