After a 4 month wait in Indiana's licensing process I am happy to say I am now allowed to carry my XD. Years ago when I bought my XD I purchased a 357SIG model because it was a round that my Uncle had enjoyed in a conversion on his Sig 229. Mine was purchased in 2003. After a hiatus from doing much with handguns I have come back to find that 357SIG ammo is fairly hard to find and pricey compared to the other rounds in my area (Indianapolis). I like the current caliber, but was wondering about getting a FireDragon 40 cal conversion barrel. From my limited understanding I believe that I would be about the same in terms of stopping power, the ammo is readily available and fairly cheap, and that if I wanted to get into reloading it would be a much easier route. I would love some input from the community as I am pretty ignorant about this aspect of firearms. I like to think I am knowledgeable about most things, but am not afraid to admit when I am not. Would it make sense to get a conversion barrel to make this a 40? If the funding was available I would just get an XDm 40 3.8 as I really like the capacity and new features. I love my current XD. I just want to be able to find ammo and be able to practice without selling the farm. Any and all help is greatly appreciated!
