It's long gone now, but my first handgun I ever owned was a S&W M-17, 6". I was 20 years old then - 33 years ago. Here in Michigan (you have to be 21 to buy a handgun from a gun shop) I had to have my brother buy it for me...then I bought it from him. It had grips on it I've never seen before or since. They were like 3/4 scale target stocks in Goncalo Alves w/the S&W medalion.
Loved this gun! It "taught me how to shoot" and after a few months and hundreds of rounds down range I could hit the cans as they rolled down the berm with regularity from 25 yards.
Thing is, at times after 6-7 cylinders the trigger pull increased substantially. If I continued to shoot without letting'er cool down the pull would increase to like 20 pounds!
I know what you're thinking....the front of the cylinder was rubbing on the barrel face as the gun heated up. Nope. Every time this occurred I checked it and there was plenty of clearance.
Whenever the happened I opened the cylinder, pushed the thumbpeice back and worked the action. Without the cylinder closed the action worked fine.
I also checked the yoke for excessive fouling and straightness. Again, squeaky clean and dead-on straight.
I've always wondered about this. I mean, I don't lay awake nights, but every now and then (like now, when I'm awaiting delivery of my 63 3") when I'm considering the purchase of a new .22 revolver it enters my mind.
Any thoughts?
