Par4QC no, but if you dry fit one you might think it would work. Ping has some very odd hosel IDs that taper down to .355 but are VERY wide towards the top of the hosel, hence the need for the collared ferrule, although IMO it's more of a bushing ferrule or built in shim then it is a collar. If we are talking the old models that don't take a ferrule then I believe those are normal .355 taper.

      ode I had a set of G5 that I sold. The guy broke a couple shafts so I cleaned the broken tips out and was going to find .355 shafts. Then I discovered that .370 would fit in 1 1/4". The graphite shafts(original) were also .370. Then while doing an online search, I came across an article that stated the bores were .370 in the later Ping irons. Seemed correct with what I had in hand. I reshafted his whole set with .370, no reaming. Just figured they were now being made like Maltby does theirs.
      It's why I asked Steve about this.

          Par4QC So, the newer will take .370?

          I'm actually not sure, now. I was unaware that ANY PING irons take .370 until you informed me. Check Maltby's chart? I'll go have a look when I get on my PC

              I just checked Maltby's shaft fitting chart. 1995-present he lists all the irons at .355

              There's a few hybrids at .370, but Maltby says PING irons are .355

              🤔
