A friend just bought himself a GP100 in .327 after buying his wife a SP101 in the same. The GP had a real good feel to it although it was the first one I've handled. I shoot a SP101 some but still prefer my pet jframe 5shot .38 Special. I don't know if it's a fluke or the 327 is becoming more common, but I noticed a local farm store stocks a couple of variations of 327 and 32 H and R mag ammo. It's a fun caliber to shoot-32 Longs are like a popgun, H and R mags are very comfortable, and the 327s are LOUD!
