I saw a sweet GP100 Ruger offering at a local shop that GOT AWAY!!
Wondered about the ability to shoot 40 S&W from the same revolver..
It did require a new set of moon clips for 40 from TK Customs..
I have the Wiley Clapp 3" GP100. I may try to pick up the Match Champion at some point too. I love the Smith 610, but like the Super Redhawk in 10mm, I think the N frame is a little overkill for 10mm. I wish Smith had an L frame in 10mm with that unfluted cylinder.
Original model 610 (no dash, pre-lock)...I purchased it new around 1991-92 at Albro's...it was on clearance since a 10mm was not very desirable at the time!
BTW, I really like the Night Guard line of S&W revolvers...that 310NG is a beautiful looking gun. I always thought I would like to buy more of them but prices have gotten too rich for me...I have a 386NG and a 327NG...regrettably, I sold my 315NG before I knew how rare it was!
