the 22/45 will obviously weigh less, but in terms of the grip and the controls, basic feel, it'll be th esame.
Well, I have a worked over NP-29 and a 22/45 and they really don't feel the same at all. The 22/45 grip is significantly thinner than 1911, the 22/45 is noticeably top heavy due to the frame being polymer and most of the weight sitting in the receiver and barrel, the trigger is not at all comparable in motion or feel (probably because the 1911 trigger moves straight back and the 22/45 trigger pivots), the safety on the 22/45 is not very easy to operate due to the sliding button design (even if it is located in the same spot as the 1911), mag changes are much harder on the 22/45, and probably more details I am forgetting.
Don't let any of this sound like I am dumping on the 22/45, it is a great pistol and I love mine. It is just not a very exact substitute for a 1911. The new 22/45 model with the removeable grip panels should be a significant improvement, because the grip feel should be much closer to a 1911 than mine with its molded in grips.
If you want a rimfire pistol that is a decent trainer for a 1911, I would say that the new GSG 1911 .22 model would be a much better choice than the 22/45 at about the same price point.
