Model 41 loss of zero?

I have two uppers for my Smith & Wesson model 41 one is a STC model that I use for a bull’s-eye with a dot and another regular upper with that I want to use for EIC competition. Should I expect loss of zero from either upper if I swap them back-and-forth on the same frame ?

Why? The sights are fixed on the barrel so my guess would be, no.

If both barrels fit correctly when installed, there shouldn't a problem switching from one to another especially since the sighting systems are mounted to the chamber and bore (barrel). Once they're zeroed they should be good.

I have two model 41's with a buncha replacement barrels with various sighting systems.  Hey!  what can I say, they are my "Fun" Guns!  Anyways, I swap barrels out with their associated sighting systems and they hold a zero just fine.  

Nuffin to worry about there pardner.

Never had an issue with the 3 barrels I have for my 41

Ditto, have 2 barrels for my M41 and I do a better job of shooting shots outside the 10 ring than the gun does!
