If you buy a new glock, get aftermarket barrel to dodge the bulged brass, bolt on a mag well, some new sites, trigger kit, etc... You can buy a 2011 . Simple economics. It's like trying to turn a Sal's ear into a silk purse. Plenty of 2011 on here for cheap. Sell your 19 and use the money to buy what you want. Besides spending money on a brand of gun you already dislike will make you unhappy when you come to the realization that you will have to sell it for half of what you put into it.
