My dealer showed me a SP101 9mm two days ago, and it looks pretty good.

I have a 4" Blackhawk Convertable that I like. However, beyond 10 yards the .38 & .357 clearly outshine the 9mm in accuracy. The "internet" says it's because the gun was designed for .38 & .357.

If I buy the SP101, should I expect it to shoot as well as a J-Frame .38 Special at say 15-20 yards?
