AS a fan of Model 27's and bigger calibers, I do not think that converting a shooter grade 27 to either 44 or 45 is "ruining" one. It is a fact ,however, that you most likely will not get your money out of it if you desire at a later date to sell or dispose of it. Also , I am no stranger to spending money on custom, caliber changes, and build-ups on everything from J-frames to 50 cal. long range rifles. You make those decisions on what you and only you want to have. My thought , if you want a 3 1/2 in Model 27 in 44 special, GO FOR IT! I personally think it is one of the neatest conversions out there. Blending a super-cool N-frame with a very practical caliber. Again search David Keith's recent posts in the thread on best combat revolvers{within the last 3 or 4 weeks} and see the conversions we are discussing and then tell me you don't think they are some of the neatest revolvers you have ever seen.
