Hate to burse your bubble, but the OP's revolver did not jam out of normal use. Yes, it goes without saying that out of spec and poorly QC'd revolvers will have reliability issues. The same is true for all firearms regardless of the manufacturer and platform.
Other than that, I'd like to see a quote from who stated "revolvers do not jam." Can you quote them here? I've never seen it, but I have seen people point out, and rightfully so, that revolvers are more reliable and dependable than semiautos assuming both are within spec. Regardless of how "reliable" you think semiautos have become, as long as the can still be pushed out of battery, are limp-wrist sensitive, and rely on its ammo, extractor, recoil spring, magazine, feed ramp, proper grip, and a bunch of other moving parts that all have to work perfectly together in sync, revolvers will be more reliable than semiautos. So Yes! Revolvers are still more reliable than semiautos in the past and present. Might be an inconvenient fact for those who perfer semiautos, but it's still a fact.
Out of the dozen revolvers I've owned within a course of the last 14 years, only one had a malfunction which was with Winchester WW 357 ammo being fired out of my 17oz Ruger LCR that jump crimp. That's not a typical concern because I and most do not carry hot rounds out of our lightweight pocket sized revolvers. It's not a concern of mine with 38spc or 357 out of steel frame or heavier revolvers.
With that said, I lost count of how many times I had a user induced malfunction (riding slide, hit mag release by accident, didn't seat the mag all the way, slide was out of battery, slide not locking back, etc) or gun induced malfunction (F2F, F2E, double feeds, etc) with semiautos. I've also have had a live round stuck in the chamber which would not allow me to pull the slide to the rear. It took 2 range officers, a mallet, a brass rod, and 10-15 minutes to fix it. I've also had the extractor slip over the rim leaving the casing wedged into the chamber. I had to borrow a brass rod to knock the casing out of the barrel.
