I currently have a 2nd gen. G22 and am contemplating building a 34 for range use and some competition. My questions are, will the LWD 34 slide work with the 2nd gen G22 frame? What is the 17L? I live in Massachusetts and cannot buy a Glock from a dealer here made after Oct. 1998. There is a limited supply of "pre ban" Glocks in the state and thus my idea to build one. Any idea what a complete upper build might cost with a non-ported barrel, internals and target grade sights? Thanks in advance.
