Hi all, Have been doing research on building a custom pistol. Just thought I would start a thread to get more info from you guys in the know. First of all, I have been mainly reading custom builds that I have found on google, But most of them are based around the 1911. This seems like a commonly used model and parts would be easier to get, But are you restricted to what caliber you can make? Like If I wanted to build a 22mag pistol (cheap ammo, easy to get), then would I be able to use the 1911 frame? After looking at the parts available it seems that most of them are .45cal. I understand anything can be done with enough work, but are there simple frames that are easily available and cost affective that can be used with such a 22mag calibre?
