Probably four or five over the years.
- PPk/s,
- S&W M66 "snubby",
- S&W 617 - 10 shot w/6" barrel
- Ruger Blackhawk in .38.357 mag <--weirdest of the bunch.. *
- Ruger Mark I
Just chalk it up to a mis-match and move on.
It's no reflection on your ability or the gun.
* The Blackhawk .357 is/was the first centerfire revolver I ever owned.
I can't shoot it worth half a squat. No one else has any problem w/it.
Now - get this - I have another Blackhawk in .45 Colt.
I have no problem shooting the gnuts off a gnat @ 25 yards with the .45LC.
