i bought a conversion barrel for my G27. shoots great, loads of fun. accurate, not even one bobble, yet, even with the .40 S&W mags. a bit of a concern. it seems quite a bit more snappy that the .40 S&W. will the xtra recoil and pressure cause any accelerated wear and tear on my beloved G27? the G27 is my primary carry piece and i wish it no harm.
