Seems like a good caliber. And I truly like the 6-shot capacity in a compact revolver. But I already have handguns in the following calibers:
22LR
380
38spl
9mm
357magnum
45acp
So, two things hold me back from the 327...
1. I already have more than enough different ammo types to stock up for. I'm not going to add 10mm or 40s&w or 327 or anything else.
2. I have NEVER seen a box of 327 ammo on the shelf of any gun shop I've been in.
