I have the S&W Governor, similar gun, better made. When I shoot 45s it is as accurate as any other revolver I have fired. Mine has two birdshot, then two PDX rounds, then two 45s and yes, I have had training.
My son-in-law and his kid just aTaurus and S%W 9mms. this weekend. Each was bragging about how they did at 50 yds., 25 yds and asked me to go with them. I put the target at 20’, used both weapons (left and right handed) with one shot each and put kill shots in. I said “You aint huntin’ buffalo with a self defense weapon.” They toned down their ranges.
