This is a great handgun the only issue I have, which is really nothing, is that you must use good ammunition in it. I\'ve used the cheap ammo and it jams, but with the better ammo like Winchester, Remington, Hornady there\'s no problems. Some people say that its too heavy, but if my wife can shoot it and you have a grip better than an infant, the weight is actually a plus. The Mark XIX can be changed from a .44 magnum to a 50 cal with a quick barrel and magazine change in about 10 sec. In California you can only get the DE44CA, you can\'t buy the .357 or 50 cal, but with all the parts being interchangeable I can order new barrels, bolt (bolt for .357 mag.) and magazines and have 3 guns in one. I did change the grip and added new fixed night sights just to make it a little better. If your a gun geek and you have lots of guns already this is a must for your collection or if this is your first handgun this weapon is like jumping in with both feet. It\'s a very cool handgun. - T.
