.22 EIC question

I have 2 M107's. A Tournament, and a Supermatic. Is it EIC legal to put the longer barrel from the Tournament onto the Supermatic? Then I have the best of both worlds. Longer site radius and frame mounted rear sight….

I have read and don’t se a single issue as long as the sight radius is not over 10 inches

My concern is that the barrel is not original to the gun however it was a catalog item at the time.

In my 27 years at Camp Perry in support of the High Standard Pistols, I have seen the Model 102 thru 107 Pistols with EVERY Type of barrel on the firing line or in my building. I beleive that there are NO restrictions on those models as they could have been ordered with any of the barrels. I beleive that factory replacement barrels are also OK. I have also seen aftermarket replacement barrels on the firing line ??? I am not sure that sight radius is even mentioned in the rules book after the Red Dot was Approved. - Alan Aronstein

Hold on you are talking about EIC not Service pistol! There is not any rules like you are thinking

Sir the dot are still not allowed in EIC and the 10 inch radius in mentioned 
They are only allowed in the 2700 part that is replacing the NRA

I was sure that I was awake when I answered that post. I guess that  I was not. Sorry for the mistake.- Alan Aronstein

Just to clarify the OP, there is no restriction on replacing the barrel on a .22 EIC pistol.  There is a restriction on sights and sight radius.
