Our good friend mc5aw, recently posed the question of which is better for a combat revolver, 44 or 45. I stated that neither 44 or 45 ,in my humble opinion, was the best. Without hijacking his thread , I will give you my thoughts, and would like to hear yours, on what comprises the design of a good/best "fighting" revolver. Keep in mind probably the best combat handgun is still an autoloader, but for 44years I have carried and trusted revolvers in the mud the blood and the beer , since I first strapped on a Model 19 in 1969 . The first thing is caliber, 357 magnum in the modern loadings works and is a good size for handguns. Second , it allows 7 rds in L-frame and 8 rds in N-frames, a decent capacity. Rivaling the 45 Gov't out of the gate{much slower at best on the reload however}. Now for the design , and keep in mind doable with existing guns on a semi-custom basis. For an L-frame , start with a 681, cut the barrel to 3 1/2 inches{full extraction] use 1/2 underlugged barrel ie. Model 27/ 38/44hd profile , fit 7-shot cylinder and round the butt and install big dot front sight with glow in the dark feature, tailor the trigger guard to Bill Jordan profile{narrow}, bob the hammer and make smooth trigger and adjust trigger pull wt to lowest possible setting and still have 100% reliability with all brands of ammo. For an N-frame Revolver, do the same modifications , only start with the older NY model 520 and install an 8 shot cylinder. These are my thoughts on the BEST Combat revolver for a serious Mud , The blood and Beer revolver. I should say if 4 legged defense is needed ,I would not argue against using 44 or 45 caliber guns and truth be told, I have been known to use one of those new fangled Gov't 45 1911 Cavalry pistols for defensive use , but at heart I am a "revolver" guy.
