Im with Deja Vu. I carry a 638 J Frame and thats one of the biggest reasons. I have in the past tried new carry pistols and have had a couple of malfunctions and when I did that pistol came all the way out of rotation. I know mechanical things mess up and there are alot of variables like ammo, bad mag...etc but once it happens its just something I personally dont feel comfortable with anymore. If I ever needed to use it the last thing I want going through my head id " I hope this thing works"...lol thats why I have stayed with the snubbie. I have never had a revolver break or malfunction on me yet.
