I guess I've not noticed it as I do not repeatedly rechamber rounds. After I shoot my 232 at the range, I clean and lube it. Then load it, chamber a round and decock it and that's how it stays until the next time I take it to the range. If not with me it is in the gun safe but I do not unload it as I see no point in doing that (I don't do that with any of my guns).
The spring is pretty heavy as it is blowback, so it is going to chamber a round with a pretty solid wack.
