After returning to the first post to make sure this was a thread about Glock 21SF models I decided I would weight in.
The Glock 21SF is an excellent firearm for a very good price. Durability, reliability, and ease of use are all excellent. The SF frame makes the grip more comfortable for most shooters when compared to the original model 21 frame. The gun is still very large, and I don't think it would be anyones first choice for concealed carry, but is an excellent pistol is you're looking for a full size duty type weapon.
