Time to clear up a longstanding misconception
For many years now, "knowledgable" shooters have opined that the old-style impinging hand Colt revolvers are somehow "delicate". I've had people tell me that they expect Colts to actually blow up because they're "delicate"!
First things first: the Colt frame and cylinder are as strong as any other revolver of a similar frame size. Period.
The lockwork, which is what usually comes in for criticism, is different than the dominant S&W design. Note the word "different" - this is critical to understanding, as the misconception seems to stem from an ignorance of the differences.
S&W lockwork allows the cylinder to rotate slightly when locked. The amount of play will vary from gun to gun, depending on a lot of factors (generation of construction, condition, abuse, etc.) The point is that even a very tight S&W has just a bit of play, and that is perfectly acceptable in the design. A S&W will in fact work well with a noticeable amount of play as long as it locks decisively.
The Colt lockwork, on the other hand, uses an impinging hand - the hand pushes the cylinder against the bolt, locking it solidly in place. A Colt cylinder, when in full lock, should NOT MOVE AT ALL. This has been referred to as the "bank vault lockup", and is what made the Colt DA revolvers famous.
This impinging hand, by the nature of the design, will wear over a period of time. The wear can occur on the cylinder ratchet, but the hand is slightly softer and will generally wear first (surface wear and compression.) This is normal, and requires occasional replacement. The user is expected to check the action regularly, and have that part replaced when it shows any sign of wear.
Now, we have Mr. S&W who decides to buy a Colt. He shoots it a bunch (and, if it was previously owned, may have already been shot a lot), and the hand starts to wear; the cylinder loosens ever so slightly. However, our shooter assumes (you do know how that's spelled, right?) that because it's still tighter than his S&W it must be OK. It's not!
If the gun is used past the point where there is noticeable cylinder play, the other parts of the action - the functions of which are all interrelated - start experiencing uncharacteristic wear, and need to be replaced. This is an expensive undertaking; Colts aren't easy to work on, and replacing the bolt alone is a painstaking task. The owner, never having even heard of anyone needing to spend that much to fix an S&W, concludes that the Colt is somehow "delicate" compared to his Smith!
If you own a Colt, learn how to do preventative maintenance. Check the cylinder lockup properly. Keep the ratchet area clean. Have the hand replaced at the earliest sign of wear. Do these simple things, and your Colt will happily digest thousands and thousands of rounds without a hiccup - mine have!
