This is an interesting trade.
I don't care for snubbies by my nature. I also don't care for Glocks... but I do own one and it's my carry gun. Same size as the G30, my EDC is a G29.
I believe as a carry gun or as a defensive gun in general, you traded down. However, in your situation--- I would probably make the same trade.
I really don't care for snubbie revolvers, but this sure is a fine looking revolver. From the single picture, it looks almost minty.
Glocks are a dime a dozen. In the time it took me to type that sentence, they made 300 more of them. These old Colts may NEVER come back.
I think you made a fine trade! I'm willing to bet that the person who made the swap may regret it one day.
