Glocks are great guns.. A 21 was my first handgun, reliable and accurate.. Just traded a 19 for a my 1911, it too was a great gun.. Had I not gotten a trade offer I couldn't pass on I'd still have it. Springfield XD's are also great pistols if your in the DAO market.
Do yourself a favor and find a way to shoot as many options as possible before purchasing, either through friends or renting at the range.
Rise and rise again, until lambs become lions....
Fear cuts deeper then the sword.
