Here's my Springer that I media blasted (slide only). I stripped everything out of the slide, carefully masked the inside of the slide - but did blast the rails. I also masked (with 7 layers of clear packing tape) the Springfield name - my ingraving under the Novak & the other side name plate area.
I didn't like the shiney buffed sides - that ALL the gun makers do. I wanted to be a little different. If I do it again, I'll just mask off the inside & my ingraving. BTW: the blasted slide nearly matches the factory finish on the frame. Thanks...
