As luck would have it, being a G20 fanatic, have accumulated a plethora, of 15 round magazines. Not to mention, the 29 trade, came with 2, 15 round mags, with the mag sleeves, that make it very comfortable, yet larger than I care for. Meaning, if I were going to carry a grip that large, would simply carry the G20. The second of the two 10 round factory mags, also wears the +2 extension as previously mentioned, which is fine, just makes the grip a little larger than I care for. Not to mention the +2 extension, does not have a lip, which I prefer for my carry weapon, to assist in draw. Especially on the smaller gripped Glock frames.
samurairabbi, I have sent you a PM!
If guns kill people, then, I can blame my pencil on my spelling!
