52
I had a model 52 a while back it was a great shooter. I sold it when I got a Colt National Match in .38 spec. from my dad. Now that is one great shooting pistol. If you can hold it it will shoot 1 hole. It likes the bullet seated out of the case 1/16 of an inch with 2.7 grains of bullseye powder behind it. If only there was a place to shoot a 2700 course around south Mississippi.
