Thanks pm with any prices
I've had several teammates with this same problem... loosens slightly after a few firm hits and needs a quick twist to tighten. Still hits like a locomotive..So far as I know, the 3/8-10 adapter is for both the original and the modified pin. I have an original pin and the adapter is a bit big (it is fine if tightened but is comes loose and you have to retighten it).
Thanks all for the replied is that just for regular or modified or both I would assume ?
