I just got one last week. Took it to the range Sunday, and went throught 100 rounds of WWB, and 50 rounds of Remington hollow points with no problem. The grip is shorter than my 239 by just a little. Since these are just the 220 Compact, without the beavertail, the baseplate from the 220 will fit, and it is about 3/16 of an inch longer. Just a little more room for your pinky, if you need it.
Since it has the shorter grip, it conceals well, and it fits in my 220 holster. So far I like it, and I don't have any regrets. It shoots accurately, and is DA/SA like my other Sigs, so that's not a problem.
