Sorry for the misleading Subject Heading.
Well, its not totally misleading.
I use these to inject "whatever" I need to
into the (pick a Gun) when I need to. I have forgotten
who it was that posted one of the Brothers Rohr
cleaning and lubing an R9s. He used a syringe to
encourage lubricant migration so I bought these
to do it the Rohrbaugh way.
If you Google
iOffer and in their search box
enter
Glass Syringe & Needles you to can
play Doctor, I mean lubricate your PUP
the Brothers Rohr way.
