I bought a pair of the 627's last year..performance shop models...one in 2 5/8" and one in 5" and they are both well made guns ( not like the traditional model 27's that I also have and love ) ...but very serviceable guns. ( 627's are all N frame, Round butt frames, 8 shots )...
I'm not an IPSC shooter....I just wanted something different ( I have about 15 of the K, L and N frame traditional revolvers model 19, 27, 28, 66, 686's in 2", 4" and 6"....and some 29's and 629's...in 3", 4", 6" and 8 3/8" ....
I even carried the 2 5/8" mod 627 in an IWB leather holster a few weeks ago...for the heck of it...
