Bawanna, Was that glock a Gen 1 or 2? I wrapped my hands around a Gen3 - 21 and the finger groves were all messed up for my hand. They were way too close together. Guy behind the table told me that Gen 1 and 2's didn't have finger grooves.
I later Picked up a XD service model in .45 (holds 13 rounds also) and if fit the hands really well and has natural point of aim.
I wish I could get a 13 round Kahr CB45 (CB is for Crazy Big.) I want the Kahr style trigger with a larger round count in 45 for around the house. Looked for a SIG P250 to try the trigger but it's only 10 rounds and I couldn't find one anyway.
