Know that there are some of y'all out there that have a much more extensive knowledge than I when it comes to pistols. That being said, can anyone give me some insight on the following questions.

1. Kimber makes and sells many different models of the 1911. in a full size model, are the inner workings manufactured alike, or are there differences in the way they are made ?.

2. Will using the 22 cal attachment for practice in anyway harm the pistol ?.

Thanks.
