Joe Chambers' excellent Barrel Fit Challenge thread got me to looking at my TRP's fit. 1) All sharpie tests were done with the pistol assembled. 2) The barrel foot/slide stop pin sharpie test shows ~25% contact on the port side barrel foot and ~5% on starboard. Sorry, no pics. 3) The stock MIM slide stop pin measures .197" at the base and .1995" at the tip. The ID of the barrel link allows a 13/64 drill bit (.203") to pass through. 4) Upper barrel lug sharpie test revealed no contact on the outer surface of the lugs, there is a fairly even line going from 9 o'clock to 2 o'clock in the recess between the barrel hood and rear lug and on the corresponding rear slide lug. It's possible the slide is being nudged to the right. 5) Barrel hood extension sharpie test reveals no contact on the left side but is showing contact on the right side of the hood. It starts at the end of the hood after the taper and goes almost half way back. Should the side of the hood be in contact with the slide? Could a slide stop with a consistent .200" pin help assuming the barrel hood fit is corrected? Thanks.
