Here is my input on the CCF frame:
I am new to the forum and this thread caught my eye since I have a CCF frame for a G22. I have had the frame for about 2 years now, with about 1,500 rounds through it, and have ran two different G22 uppers on it, one from a Gen 2 and one from a Gen 3 Glock, and have had not one problem that I can relate to the frame.
I have the stainless frame and like the extra weight as it helps me specifically with controlling the recoil and staying on target.
I am currently building a complete "CCF22" 0.40 SW gun with their CCF upper and CCF barrel; Larry at CCF is a great guy to work with and he stands behind his product. I have never had an issue communicating with Larry and will continue to do business with him since he has shown that he is a man of integrity.
Thanks.
