I have a Glock 17 gen 3 I'm thinking about getting a Cominolli external safety installed in, and I wonder if you carry these safeties and/or would be willing to install one? If so, can you quote a price for each? Tried calling you several times, but couldn't get through.
We do not stock them, and will not install them since it requires modification (i.e. cutting) of the frame.
My advice is if you want a gun with a manual safety, buy one designed with that feature from the outset, rather than trying to turn a Glock into something it's not. I would suggest looking at the Ruger SR9, or the S&W M&P (with optional ambi safety). Both are striker-fired guns like the Glock, and are proven designs with a good track record.
