I'm not so sure either manufacturer knows what they're trying to do. Now, a Colt story:
A few years ago in an out of state rural gun shop I was just 'passing through' I found a very high condition New Frontier 22 in blue and case color. Sadly, the 22 mag cylinder was nowhere to be found, but the gun was priced right. After the usual hoop jumping involving two FFL holders, shipping, my county sheriff, the state police, character references and senate confirmation, I finally owned it.
One chamber shaves lead. Thank you Colt. The gun should have been delivered with a full face shield.
Then the mainspring broke.
Perhaps someone can explain the 'design feature' I found.
The flat mainspring fractured along a 'score' line close to the bottom of the spring. That's right. A score line, where the spring steel is scratched or machined all the way across the spring.
I ordered two new springs so as to have a spare, and both new parts have the same score line.
It's as if they WANT the spring to break.
Now, what's up with that?
