I have both the 20 and 29 I like both my 29 is my second most carried gun . I carry it when going down town, when walk security at church any place I consider higher risk. Both my guns run 40 S&W fine Glocks big extractor catches the rim and holds it so it headspaces off the rim. They shoots them well enough that I would not hesitate to load up with 40's if I didn't have 10 mm ammo.
Every breath I take as a Free man was paid for with the blood of an American Soldier
