Your joking of course! With factory ammo at approx $47.00/50 rds, you had better be into volume bullet casting and reloading .38 S&W. If your thinking of an inexpensive revolver to shoot IPSC with, try a used "K" frame S&W or GP-100 with .38 Specials.
Years ago, I shot 1 full year of IPSC with a S&W M66 using .38 Special +P loads and it was the most fun that I had in the 10 years that I shoot IPSC.
