I have one of each. A Taurus 651 (357 5-shot shrowded hammer) and a Glock 36 (45acp 6+1).
I use both for carry, but find I can shoot the 45 better. Also, I find the 357's to be so loud while shooting normally, I'd hate to find out what my ears felt like if I ever had to use it w/o protection on. Because of this, I carry my 45 the majority of the time.
If i can get my hands on one of the 327's, it would likely become my new carry gun. I just prefer a wheelgun for carry, so long as I can shoot it well.
Ultimately, pick which appeals to you the most, or whichever you are better with.
